How much difference could a simple Banana plug make?


Well - I've tried several different types of Banana connector over the past 8-10 years and although there were subtle improvements from one plug to another, there was never any "remarkable" improvements.

That was - until yesterday !

My - how things changed :-)

If you search the forums, you'll find several posts and reviews by me touting the benefits attained by using products from KLE Innovations. I like them a lot and consider them among the best products in the market.

The  KLEI™Classic Harmony Banana Connector/Adaptor is not just "another Banana Plug"

https://kleinnovations.com/kle-innovations-klei-products/klei-harmony-banana/klei-classic-harmony-ba...

To start with, it is designed to be multi functional - you can use it as...
- A single Banana Connector
- A stack-able Bananas Connector - e.g. it allows you to easily attach jumpers  when connecting a single cable to a bi-wired speaker 
- A Banana Adapter - e.g. as a temporary connection of bi-wired cables to a single wire speaker i.e. without leaving one set not connected.

There may also be other uses that I am yet to discover.

What makes these plug so special
1. they boast an impressive IACS conductivity rating >101%  - that's impressive for a copper product
2. they are engineered to allow another banana plug to be inserted into the insulated housing
3. they have perfectly round spring pins - most spring pins are not completely round
4. they fit into all of the banana terminals I have tried with an unforced "snugness" that grips the speaker and amp terminals securely.
5. they are dead simple to connect using solder
6. removal is also very easy if you want to try them on a different cables

KLE Innovators state they can be crimped, but that's not something I would personally try - perhaps that have a special crimping tool?

So how did this unassuming looking little banana improve sound quality ?...
1. the most noticeable improvement was the width and depth of the image - much bigger than my room
2. overall clarity was front and center and added some nice "sparkle" in the high end
3. instrument placement and isolation within the image was improved
4. The dynamics were noticeably faster.
5. additional texture in bass lines were very nicely reproduced

I think the best genre of music that shows off the full capability of these bananas is classical - even my worst recording sounded very spacious and allowed be to discern the distinct boundaries of first/second viollins, violas, cellos and double bass sections within the orchestra and the added depth placed brass, woodwind and percussion in equally isolated spaces front to back within the image

"Is This Love", by Bob Marley was cavernous and sounded like it was being performed in a stadium!

These connectors also excel in allowing micro details such as subtle venue reverberations and reflections to be more noticeable than with any other banana connector I have used in the past.

If the speaker cables in your system utilizes a more standard Banana plug -  I'd highly recommend replacing them with the KLEI Bananas.

Cost is $135 Aussie Dollars (about $100 US)

What did I use before these?

The most recent was a spring connector from ebay like this
https://www.ebay.ca/itm/4x-Acoustic-Copper-Silver-Plated-APS5-Speaker-Cable-Banana-Plug-Connector/30...

Other "named" products included Spring Banana plugs from Neotech and a pure copper connector from Furez - none of which performed to the level of this plug

There are not many products that improve sound this much for $100 - go on - give em a try!

Back to the tunes :-)

Good idea and amazing what a effect a connector can have on the sound.  Their products are definitely excellent that is for sure and it sounds like the KLEI banana is exceptional, also. Thank you for the update.
Maybe I will try them on the gZero6 SCs that I have although I really like them as they are already.  Food (bananas) for thought...
lak, contrary or not, that is a terrific and can you describe in a more detail the sound improvement.

williewonka, you still seem really happy with the sound improvement... very detailed, quick, and fast burn-in.

I read that a fellow inserted the classic harmony banana on to a pair of Nordost blue heaven speaker cables that already have bananas and the sound improved, quite noticeably. That is pretty amazing and sounds like the effect that Bybee quantum thing-a-me-bobs have, but it would appear even more so and much cheaper. https://kleinnovations.com/wp-content/uploads/2017/12/20171216_KLEI-Classic-Harmony-Banana-by-SS_1.1.pdf

Maybe this is a quantum device in the form of a banana. Anyway, it all sounds good and worthwhile. Sounds like it’s time for the gzero6 cables to be quantumized and it sounds like a good thing.


williewonka, quantum banana, sounds better and interesting.  I have ordered them so might try as an adapter, first. That will cook them.  How many burnin hours would you recommend?


lak, $107, is pretty reasonable, not cheap but not expensive.

I was asking about the other expensive bananas that you mentioned. What ones are they?
These bananas are amazing. I received them and simply inserted them onto the existing bananas (as an adapter) and right from the very beginning the sound was better. Letting them settle and burnin, by just playing music (about 70 hours so far), the sound got even better. The improved sound I have been listening to, is noticeably better...
- upper bass and lower mid weight and resolution
- articulation, resolution, and clarity
- leading edge attack, speed, excellent PRaF
- harmonic texture

The KLE Innovations classic harmony bananas are very easy to use and, imo, excellent bang for buck. Quite amazing actually.
@williewonka & @lak from what I am hearing, and enjoying very much, I am finding the KLE Bananas to be a no brainer. The sound was already musical but it is now really, really, musical, if that makes sense. I am enjoying them so much as an adapter that I am happy to take my time changing the bananas that are already on the SCs. Actually, I may just leave them as they are as I not feeling in any hurry to change them. HNY to all
which Neutrik bananas do you like and why to you like them?

Guys, not great with words but what I meant to say was that I was already enjoying listening to my system but now I am enjoying listening to my system, much more. Anyway, quite amazing, interesting, and HNY
williewonka, I am still using these as adapters, attach to the existing bananas and they still sound great.

I would almost describe the effect they have as quantum. quantum has a nice ring to it, quantum, quantum, quantum. not sure what that means but it sounds good and they sound great as opposed to just good.

From posts I have read they seem to go very well with dueland wire and your helix wire. good find and thanks for letting us know.

Have the sonics further improved? have you had any issues with them?
williewonka, have you tried the Furutech CF-202R.  on sale for 8 of them, they are 6 times the price of the KLE.  wonder how good they are. 
williewonka, I have found them to be great used as you have used them, as an adapter.  It is great that they work sensationally well when used this way.  I have used them inserted onto MC bananas.  The sonic improvement is quite noticeable, even dramatic.  How about that.
