DiY Cables

"The HELIX IMAGE" - With a little help from my friends

This Page is an overview of the very latest developments and updates to the Helix Cable Geometry
Last Update: APRIL 2021.

NOTE: For Helix Cable/Component compatibility - please see HELIX Q & A

The latest development features an approach of changing the insulation on the the
Signal and Live conductors in the Helix cables.

During the most recent developments, it was quite noticeable that selecting wires that had an insulation with a low
Dielectric Constant (Dk) for the signal or live wires only resulted in improved sound quality

Dielectric Constant (Dk)…
  • Dielectric constant, property of electrical insulating material (which is a dielectric) equal to the ratio of the capacitance of a capacitor filled with the given material to the capacitance of an identical capacitor in a vacuum without the dielectric material.
  • PVC: Dk = 4.0
  • Teflon: Dk = 2.2
  • Foamed Teflon (AirLok): Dk = 1.45
  • Cotton: Dk = 1.3
  • Air: DK = 1.1

So the challenge was: how to get the Dk as close as possible to the value of Air?

The adaption to the insulation can be found here…

The HELIX IMAGE (Air)


Applying this approach to the insulation of the Live or Signal wires of HELIX IMAGE cables resulted in improvements to every single metric we use to assess system performance…

  • Dynamics, Clarity, Details, image size, image focus, space around performers
  • outstanding clarity and details together with improved precision within the image
  • the depth of the bass was deeper with improved textures.

For Interconnect Cables see…
For the USB USB Cable see…
For the Speaker Cable see…
For the Power Cable see…

I am currently using HELIX IMAGE (Air) cables and can report that the modifications have resulted in significant and easily discernible audible improvements over the older design.
I have listed a few options of wires that can be used for the signal and neutral wires in the detailed fabrication instruction, but the digram below shows which wires I use and for which components

System Cables


The original helix design concept was to eliminate the parallel conductors commonly used in conventional cable architectures in order to minimizes the noise, proximity effect and Skin effect to imperceivable levels, improving clarity and dynamic performance of the interconnect.

Since those early days, developments include the selection of advanced wire metallurgy, gauge of wire best suited to the task at hand and types of insulation in order to reduce noise to a minimum, which brings us to this moment in time.

The instructions on this web site demonstrates how these cables can be fabricated in the easiest and most cost effective manner in order to achieve extremely high levels of resolution that competes with the very best commercially available products for a fraction of the cost.

Previous adaptions to the HELIX Cable are courtesy of:
  • long time contributor on the Audiogon Forum: Member Name: Grannyring (i.e. Bill) - for his Schroeder Double Shotgun approach
  • Ernst of Austria - who first brought my attention to the importance of Dielectric Constant
  • Yordan & Evgeny of Bulgaria - who test numerous wires containing different metals and insulations
  • Todd (US) for developing the first bi-wire version of the Helix speaker cables
  • also, Ghislain (Canada), John (USA) and many others.

Will there be any further updates - probably, because there is always someone, like Bill, Ernst, Jordan and Evgeny that is looking to improve on the capabilities of “The Helix” cable geometry.

“The HELIX IMAGE (Air)” - these cables now convey the most realistic and compelling image I have ever observed in any system

The level of detail and clarity, together with precise location of performers and an image that envelopes the listener is stunning


If you have any further questions on these upgrades just drop me a line.

The HELIX IMAGE (Air)

NOTE: This page ONLY describes the process of insulating the Signal or Live wires of the Helix IMAGE cables.
  • strange as it may seem, you DO NOT have to apply this insulation guide to the Neutral wire

Links to the pages on how to build the individual cables can be found at the bottom this page


So How do you build a conductor that has Air as the dielectric?

Teflon tube has been a long time favourite in my cables (early on) so I looked back a previous versions of the cables and realized if I used the right sized tube it would allow enough air around the wire and result in a very small area of contact.

I selected a PTFE Tubing with Internal Dia = 0.106" and Outside Dia = 0.130" - from Take Five Audio

This tube can be used for either
  • a single 14/12 gauge wire when used to fabricate the Signal or Live wires for the speaker cables and power cables
  • or the 2 x 18 gauge (for Interconnects) and the 2 x 16 gauge (for SOURCE power cables)
  • so basically, this teflon tube it is suitable for all Interconnect, speaker and mains cables

Looking at the diagram below, of the cross section of a Live conductor of a mains cable and a twisted pair signal conductor of the interconnect cable it is quite clear that provided the tube does not collapse there is only ever ONE point of contact with the teflon tube, with lots of air around the actual wire

This is the value Teflon has over Cotton and Silk sleeves, because cotton and silk tend to collapse around the wire resulting in multiple points of contact, increasing the value of the Dk



00 cross section


Unfortunately, the UP-OCC copper I have been using from both Neotech and VH Audio both have insulation that must first be removed, but bare UP-OCC wire can be purchased from retailers such as Part Connexion

In order to remove the insulation with a minimum of effort I inserted an eye ring in the end of a piece of wood (see below) to make a simple striping jig

  • Thread the wire through the eye ring
  • hold the wire on the board at the other end of the board
  • Place the blade of a utility knife on the wire and lift the blade to about a 5 degree angle
  • and simply cut a small sliver of insulation from the wire
  • then peel the insulation from the wire


01 board

The rest of this process depicts how to fabricate the Signal conductor for the Helix interconnect
  • which uses 2 x 18 gauge wires
  • but the same process can be applied to any HELIX IMAGE (Air) Cable



FOR the 2 x 18 gauge Interconnect SIGNAL CONDUCTOR
AND the 2 x 16 gauge Source Power Cables LIVE CONDUCTOR


Strip the insulation from the two wires (as shown above) and twist one end tightly to hold the wires together

02 twist tight

Then twist the two wires together at the rate of about one complete twist every 3-4 inches

And twist the last 1/2" or (centimetre) to prevent the wires from untwisting, as below


03 twist loose

Then insert the tightly twisted portion into a drill chuck and hold the other end with a pair of pliers

04 drill

Rotate the drill clockwise i.e. clockwise as you look down the wire from the rear of the drill

Rotate until the wire is evenly twisted - approximately 3 twists per inch - as below


05 Drill Twist

Remove the wire from the drill chuck - it will remain twisted, but tightly twist the end to match the the opposite end

Then "TIN" the wire with solder for about 1" at each end - this prevents oxidation outside the Teflon tube


06 tin ends

Insert the wire into the teflon sleeve and apply a small piece of heat shrink tubing that has the adhesive on the inside

An optional alternative is to seal the ends with hot glue

This seals the tube and prevents air flow and prevent oxidation of the bare wire


07 seal ends

FOR the 2 x 16 gauge Speaker Cable SIGNAL CONDUCTOR
AND the 2 x 14 gauge (heavy duty) HD Power Cables LIVE CONDUCTOR


A similar process is required, except that each of the two wires is inserted into it's own tube and then gently twisted as shown below
i.e. approximately 1 complete twist every 4" (10cm)

Speaker-Live


The Power Cable LIVE conductor is terminated with a spade and both tubes are sealed with a single piece of Heat Shrink as show below.
Only attach the speed at one end to allow for easy insertion into the Helix Coil and then attach the other spade



Power term

Using this technique, a view of a cross section of the twisted pair conductor reveals…


Twisted Pair X


This provides an additional benefit when the twisted pair conductor is placed inside the Helix Coil of the speaker cables





No Beads

If desired the conductor assembly can be placed inside a cotton sleeve for improved vibration control, but it is NOT required


So why prevent air flow?
  • In order to prevent the bare copper wire (or silver) from oxidizing
  • Initially some oxidation will occur and a little dullness will result
  • but based on my current speaker cables which have been in place for about 4 months, the dulling of the copper appears to have stopped

I was initially very concerned about oxidation because if it was a real issue it meant people would be faced with re-wiring their cables once they turn green.
  • But on thinking about the oxidation process further, those copper weather veins on buildings generally take about 5 - 7 years to obtain the green patina
  • they are open to the elements 24/7.
  • Also, the bare ground wire in my house (that connects to the water supply) is still pretty bright after 4 years
I believe sealing the wire inside a Teflon tube using the approach above will protect the wire from oxidation for a considerable period of time. i.e. many years

In recognition of the superb performance achieved by applying this technique I have decided to name this versos of the HELIX cables…

The HELIX IMAGE (Air)


When this approach is used on all Helix cables the results are stunning !!!


So In Summary

  • Interconnect Cable Signal Wire is 2 x 18 gauge UP-OCC twisted wire inside a single Teflon Tube
  • Speaker Cable Signal wire can be either 2 x 16 gauge or 2 x 14 gauge, where each wire is in it's own Teflon tube with a gentle twist
  • Source Power Cable Live wire is 2 x 16 gauge twisted wire inside a single Teflon Tube (see warning below)
  • HD Power Cable is 2 x 14 gauge Live wire where each wire is in it's own Teflon tube with a gentle twist
  • The neutral and ground wires are unchanged from the original design

WARNING: You may be tempted to use a single tube on the speaker cables if using 2 x 16 gauge wire, but it becomes increasingly more difficult to insert the twisted conductor into the tube after about 4-5 feet

This technique can be applied to any of the following HELIX IMAGE Cables…
Interconnect Cable...
USB Cable...
Speaker Cable...
Power Cable...

KLEI™Classic Harmony Banana Connector/Adaptor Review

After what seemed like an extraordinarily long R & D effort, KLE Innovations has released the long awaited KLEI™Classic Harmony Banana Plug/Connector & Adaptor .
KL had “hinted” a while back that these connectors were in the development stage.
Small Crystal

Well, as with all things designed by Keith Louie Eichmann, attention to detail is paramount and this “philosophy” is evident by close inspection of these banana plugs with the housing removed.

As can be seen:
The design utilizes a double barrel design, with one barrel being just under half the length of the second barrel.
KLEI Banana Plug_DSC_6899_01

Use a toothpick to wedge the wire in the banana plug before soldering
Solder
  • The shorter of the two barrels is normally used to attach the cable (up to 4mm in diameter).
  • There is a small shoulder half way down the longer barrel of the plug, allowing for a second Banana to be inserted into the rear of that barrel.
  • This allows for the “stacking” of plugs - a very convenient feature for attaching jumpers on speakers with bi-wire terminals while using a single-run speaker cable.
  • The shorter barrel can also be used to attach a second banana plug (provided a cable has not been attached), which is a very convenient feature for temporarily connecting a set of bi-wire cables to a speaker having only two connecting terminals.
  • This feature prevents the plugs on the second cable run from flapping around waiting to “short out”. In this scenario the plug is acting more as an adapter.

STACKED CONNECTORS:
KLEI Banana Plug_DSC_6901_01KLEI Banana Plug_DSC_6895_01

So what else makes this plug so special?
  • They boast an IACS conductivity rating >101%  - which is impressive for a copper product, since copper is normally rated at 100% and Beryllium Copper, a material of choice for this style of connector by many other brands, has an IACS rating of between 40%-60%
  • they have perfectly round spring pins - most spring pins are not completely round which allows air gaps that may be prone to micro-arcing.
  • they fit into all of the banana terminals I have tried with an “unforced snugness" that grips the speaker and amp terminals securely, which is probably due more to the ‘friction element’ of the snug fit, rather than the amount of spring in the clip.
  • they are very simple to connect to cables using solder and removal is also very easy should you want to try them on a different cables.
  • Having the second barrel to connect the wire to makes it almost impossible to run solder into/onto the “business end” of the plug - something other manufacturers should consider.
  • KLE Innovations states the bananas can be crimped, but that's not something I would personally try with my crimping tool - I’ve tried crimping spring style bananas in the past and the result was less than satisfactory.

The KLEITMClassic Harmony Banana Plug/Connector & Adaptor, like other KLE Innovations products, are silver finished, not Gold or Rhodium, which is a feature some people could consider less than optimum due to its tendency to tarnish over time.

My response to those concerns :
  • I have been using KLE Innovations connectors (RCA’s and Bananas) for close to 4 years and I am yet to see any sign of tarnish under normal use, i.e., household humidity between 40% - 65%.
  • Any other finish will impact the overall IACS rating, which will degrade performance.

Connecting the cable is extremely easy:
  • remove the plastic outer housing from the plug.
  • Strip 4-5 mm of the insulation from the speaker wire.
  • KLEI Banana Plug_DSC_6898_02
  • “tin” the bare wire with solder - i recommend WBT (4% silver solder), ‘Wonder Solder’ or equivalent.
  • insert the wire into the shorter of the two barrels ensuring the tinned end comes to the angled end of the shorter barrel.
  • KLEI Banana Plug_DSC_6899_01a
  • solder the wire in place by applying solder at the angled end of the shorter barrel and leave to cool down.
  • re-insert the banana into the plastic housing - Note: it only fits one way.
  • fold the small plastic door into place and press and ensure the locking tags click into place - VOILA!

Being a proponent of
“Less is More”, I leave insulation on the wire such that it too will be inserted into the barrel as well, which effectively prevents the the solder from filling up the barrel.
  • KLEI Banana Plug_DSC_6900_01

In the case where a thicker wire is used, I remove enough insulation so that the flap on the housing can close, but I add a piece of heat-shrink to
prevent the the solder from filling up the barrel and insulate the exposed conductor.
KLEI Banana Plug_DSC_6906_01

The finished result is a neat connection with no possibility of an accidental short circuit

How do I remove the plastic plug housing once the flap is closed?
If you wish to open the small flap at the back of the plug housing once it has been closed, you can simply...
  • Insert another Banana Plug into the plastic housing part only
  • PLEASE ENSURE the banana plug is NOT inserted not the metal barrel part of the plug as it may damage the plug
  • GENTLY pry the flap open
  • I recommend that you use an old Banana Plug to do this and NOT another KLEITMClassic Harmony Banana Plug/Connector & Adaptor.

KLEI Banana Plug_DSC_6902_01KLEI Banana Plug_DSC_6903_01

What if the plug slips out of the Binding Post?
Since binding posts do not adhere to a strict “standard size” for the hole, the fit of the KLEI Banana Plug may not be snug enough to prevent the weight of the cable from pulling the plug out.
Should this be the case, you can simply enlarge the size of the barrel by inserting another banana plug into the barrel for 5-6mm
  • PLEASE NOTE: you want a snug fit, i.e., the plug can easily be inserted into the Binding post.
  • So try 2-3 mm to start with and work up 1 mm at a time until the desired fit is achieved
  • EXCESSIVE FORCE should NOT be required to insert the KLEITMClassic Harmony Banana Plug/Connector & Adaptor into a binding post
  • Rotating the KLEITMClassic Harmony Banana Plug/Connector & Adaptor while inserting it is NOT recommended under any circumstances.
KLEI Banana PlugDSC_6907_

So, How do They sound?

The package the plugs arrive in states that the
KLEI™Classic Harmony Banana Plug/Connector & Adaptor will require a 125 hour burn-in period to sound their best!
  • But if your experience is anything like mine, they will improve your sound immediately.
  • and then continue to get better over time.

SIDE BAR:

  • I have observed throughout the reviews I have conducted that any improvements observed can be impacted by the quality of the components and cables that a newly installed piece of equipment or connector is connected to.
  • In plain language - installing these Bananas on lamp cord speaker cables purchased at the local hardware store will probably NOT dramatically improve the sound of your system!
  • However, these connectors are capable of conveying details to an extremely high level of resolution and as such should be installed on cables of a similar resolution capability.

Moving On...
I was very surprised to hear an immediate discernible improvement across the board, since many products, regardless of brand, normally require a little time before they start to
“step up to the plate”.
  • It was one of those moments when you turn on the system and start streaming content from internet radio stations to begin the burn-in process, only to be “persuaded” to switch over to a source of a higher quality because of “something” very interesting you have heard.

That “something” was - outstanding clarity!


The trip through the content of my library also revealed...

  • a larger, more well defined 3D image with more precision in instrument/performer placement and isolation.
  • a faster dynamic performance across the board, resulting in more sparkle at the top end and more texture in the mid and bottom end.
  • Classical recordings tended to demonstrate the extraordinary imaging the KLEI™Classic Harmony Banana Plug/Connector & Adaptors are capable of, simply by providing superb isolated placement of violin/viola/cello/double bass across a very wide image, combined with placement front to back of strings/woodwind/brass and percussion sections to such an extent that left me feeling I was actually sitting in the concert hall.
  • The presentation of Is This Love by Bob Marley seemed as cavernous as a large stadium.


But Could the KLEI™Classic Harmony Banana Connector/Adaptor improve more with burn-in?


In short - very much so!


And so, I turned to my vinyl for a more detailed audition...

The album that had some of the greatest impact was
“The best of Dire Straits & Mark Knopfler, Private Investigations” - a nicely engineered double LP set on heavier vinyl.

  • The superb clarity and detailing on Sultans of Swing made for a mesmerizing listening experience.
  • The dynamics of Mark Knopfler’s guitar work on Money for Nothing were perhaps the fastest I had heard.
  • Yet the soft textures of his voice on Brothers in Arms was ethereal.

By contrast, a couple of albums from the mid 1970’s highlighted another attribute of the
KLEI™Classic Harmony Banana Plug/Connector & Adaptors - their smoothness...
  • Jethro Tull’s - Songs From The Wood and The Steeleye Span Story had always sounded quite shrill, so I was expecting an even brighter performance. However, the harshness of both of these albums seemed to be tamed and the music had much more body and depth without sacrificing the very crisp dynamics.
Stevie Wonder’s Talking Book is a well played favourite in my review process, mainly for the track Superstition...
  • In the opening scene of the movie I Robot - Will Smith plays this track on a futuristic audio system.
  • Of course, with the enhanced sound engineering and Dolby Surround Sound cranked up - it sounds incredible!
  • So I figured that it might be a good track to truly test the abilities of the KLEI™Classic Harmony Banana Plug/Connector & Adaptors.
  • The reproduction of sound from this old piece of vinyl was spectacular - a crisp, fast, full bodied, deep, clear listening experience.
  • This album, a favourite for years, seemed like it had been completely re-mastered.

One last album where the
KLEI™Classic Harmony Banana Plug/Connector & Adaptors delivered an outstanding performance is a TACET recording of Paul Florin (violin) playing Partitas by Johann Sebastian Bach.
  • This album demonstrated just how much “space” these connectors are able to convey.
  • I was transported into the church where the recording was made.
  • reflections bouncing from wall to ceiling to wall getting fainter with each reflection.
  • Just me and Paul Florin - an experience I am now able to re-live again and again.

I could go on dissecting and analyzing each album in my library , since it was as though the
KLEI™Classic Harmony Banana Plug/Connector & Adaptor had re-mastered every piece of vinyl.
  • Classical albums best demonstrated their ability to cast a very large image in 3 dimensions.
  • Jazz vocals conveyed superbly soft velvety tones.
  • Pipe organ music demonstrated the amazing control the amp now had over the speakers with superb dynamic textures across the entire frequency range.
  • Pop and rock albums served up dynamic drums and crisp bass lines like never before.

Not to be left on the side lines, one of the nicest improvements was the very analogue presentation now produced by my Bluesound Node 2 digital streamer, since all traces of “digital” had now been vanquished, leaving only an extremely enjoyable listening experience.

Should I have expected anything less?

Perhaps not, especially considering my prior experiences with other products from
KLE Innovations that I have reviewed over the years, that have proven every single time to provide outstanding improvements in sound quality.


But all this from a little Banana plug soldered onto the end of my speaker wires? - really?

Well let’s be quite clear, the KLEI™Classic Harmony Banana Plug/Connector & Adaptor is not just “a simple Banana plug”...

  • it’s fabricated from high tech modern day materials whose metallurgy is a closely guarded secret.
  • it’s designed to exacting specifications.
  • it’s manufactured to extreme engineering tolerances.
  • It really is...

The “F22 Raptor” of Banana plugs!


Much like the Harmony RCA Connectors also designed by Keith Louie Eichmann, the
KLEI™Classic Harmony Banana Plug/Connector & Adaptor is capable of much more than simply holding a cable in a hole.
It will revolutionize the Banana Plug, just as the Harmony RCA Connectors have revolutionized RCA plugs.

The KLEI™Harmony Banana Plugs (ClassicHarmony and PureQHarmony bananas), are standard on the new KLEIQSeries speaker cable models (QFLOW2/Classic, QFLOW3/PureQ, QFLOW7/PureQ, QPURITY8/PureQ SCs) but not on the current gZero and zPurity models.
For the current gZero and zPurity speaker cable models you will probably be able to have them installed at additional cost – contact
KLE Innovations before ordering.


How can it be used as a “Connector & Adaptor” ?

To this point I had only auditioned the KLEI™Classic Harmony Banana Plug/Connector & Adaptor as a simple banana plug installed onto my speaker cables.

But as the name implies, the KLEI™Classic Harmony Banana Plug/Connector & Adaptor actually provides additional flexibility in areas where other “connectors” fall short.

Screen Shot 2017-11-18 at 10.37.14 AM

For Example...

KLEI Banana Plug_DSC_6895_01

It is very simple to create quality bi-wire jumpers, to allow the use of single run speaker cables with loudspeakers that have bi-wired terminals, without having to “reconfigure” the actual cable in some way.

The existing banana on the speaker cables can simply plug into the back of
KLEI™Classic Harmony Banana Plug/Connector & Adaptor on the link itself.

Or...

If you are using bi-wired speakers with bi-wire cables, but only have a single pair of binding posts on your amplifier, you can simply insert the banana plug into the binding post of the amp and then insert both bananas of your bi-wire cables into the
KLEI™Classic Harmony Banana Plug/Connector & Adaptor, again, without having to “reconfigure” the cables. Basically it operates as an adapter

Or...


If you need to hook up a subwoofer via the loudspeaker terminals, the
KLEI™Classic Harmony Banana Plug/Connector & Adaptor can be attached on the speaker cables and the subwoofer cables at the speaker for easy installation.

Now, you might be thinking that “stacking” banana plugs for either of these scenarios could cause some degradation of the audio signal.

After all, it is “generally accepted” that sound quality improves when there are fewer “interfaces” in the electrical path. Adding interfaces is bound to degrade performance to some degree?


However...

The
KLEI™Classic Harmony Banana Plug/Connector & Adaptor, as it turns out, is far more advanced that any other connector I have encountered, in that...


it can actually improve sound quality when used as a simple “interface” between the binding post of an amplifier or loudspeaker and the existing banana plugs on a speaker cable.


Huh - ???


That was my (initial) reaction!

How can

adding a banana plug “interface” into the signal path improve sound quality?

And, if you think about it
It is actually two banana plugs
One at each end of the speaker cable!


But when Keith Louie Eichman (KL), requested I audition the
KLEI™Classic Harmony Banana Plug/Connector & Adaptor as in this very scenario, and “hinted at the possibility”, OK “strongly inferred”, that I would hear discernible improvements, let’s just say there was “some degree” of ambivalence - on my part.

So, setting aside my ambivalence, I installed a new set of the
KLEI™Classic Harmony Banana Plug/Connector & Adaptor’s into the binding posts of my speakers and amplifier, that are part of my Audio/Video system, and listened to them throughout the burn-in process.

  • The connected components of my A/V system is a Bluesound PowerNode 2 digital streamer/amplifier and Tannoy Mercury Fusion 4 tower speakers.
  • Not perhaps the highest resolving components out there, but solid performers that punches above their “weight-class” due to the installation some many months ago of high performance power and speaker cables.
  • The existing bananas on my cables are of the tubular spring variety and silver plated.

Initially, I was unable to discern any immediate improvements, but then again, there was no sign of sound quality degradation either.

As I listened, the recommended 125 hours burn-in period seemed to shorten, as some improvements seemed to materialize earlier than I had expected...
  • at around the 80 hour mark there seemed to be improved focus and improved artist placement within the image
  • at around the 100 hour mark the upper register of violins and cymbal reproduction had more body and tone and were far smoother than before
  • by the time the 125 hours has elapsed I was also able to discern improved clarity and just a hint of improved dynamic performance and the warmth at the high-end had permeated thought he mid frequencies also

For me, most developments in the world of Audio/Hi-fi have a rational explanation e.g.
  • why one amplifier sounds better than another - better power supplies, capacitors, etc.
  • why one cable sounds better than another - better materials and geometries etc.
  • why one connector sounds better than another - better materials, better clamping etc.

But why the
KLEI™Classic Harmony Banana Plug/Connector & Adaptor improves the sound of existing cables/bananas has left me without explanation and KL has not offered any insight, other than to say it is due to his proprietary formulation and advanced manufacturing processes.

If I were asked, prior to performing this audition, if I thought a “connector” could improve sound quality when used in this manner - I would have said NO!

Now - I have a very different opinion.

Would I recommend using
KLEI™Classic Harmony Banana Plug/Connector & Adaptor’s in this manner as a simple “adapter” ?

Well - that’s a tricky one...
  • after all I do promote the use of quality connectors that screw on
  • in this case it is just a push-on “adapter” - so to use as a proof of concept - perhaps yes

For me, this audition has proven that using the
KLEI™Classic Harmony Banana Plug/Connector & Adaptor for bi-wire applications, such as those above, is without any risk of degrading sound quality and would in all likelihood would prove beneficial.

So, as it turns out the name of this banana is actually very well suited.

The
KLEI™Classic Harmony Banana Plug/Connector & Adaptor is just that...
  • A Bananas plug
  • A Connector, and
  • An Adapter

  • But far more than that...

It’s an incredible achievement!

Summation...

It took a while to bring the
KLEI™Classic Harmony Banana Plug/Connector & Adaptor to market but, I have to award kudos, to Keith Louie Eichmann and his team - for taking their time to “get it right”.

The
KLEI™Classic Harmony Banana Plug/Connector & Adaptor appears to allow every detail and nuance of the recording to be conveyed with amazing clarity and dexterity - something I have not observed to this level in any similar product.

They really are - THE Banana Plug you want at the end of your speaker cables !


I give them my “Best Bang For The Buck” award.
