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 :-)

I've not tried klei cables, as your designs are the sh*t, willie, but man, I love his RCAs. Such simple, effective design. A great way to terminate Willie's helix design!
@toddverrone - KLE Innovations cables were the "yardstick" by which I gauged the performance of the Helix cables.

I have found that there are people that love to try DIY stuff, like yourself, and others that feel they lack the necessary skills - in which case I have no problem recommending KLE Innovations products - not only are they great performers, they are reasonably priced, i.e. compared to the competition in the market place.

If you "love" his RCA’s - when you see the simple elegance of his design "in the flesh" - I think you’ll go bananas (I’m really sorry, I just couldn’t resist) :-)

Cheers

@yping - when Keith Louie sent news of the release of the new Bananas I was in two minds...
1. how could a simple banana be capable of improved sound quality, after all it’s such a tiny piece of metal.

2. It’s Keith Louie Eichmann, inventor of the Harmony RCA - again a simple connector that has proven itself to me and many others over and over.

The harmony RCA’s provided benefits from the get-go - so why not the Banana?

Well, I’ve just completed the 125 hour burn-in process and I can report...

A. they provided very discernible improvement from the start

B. There as little improvement from my initial observations over that time, but to be honest I did not really stop and listen

C. Yesterday evening I did have an opportunity to sit down and listen intently to some of my well recorded tracks and found that over and above my initial observations they now exhibit a fuller/richer, more complete sound, the details of which I will get into in my review that will be posted here next week.

I recall you’ve used KLEI products in the past and I know you were impressed - I think these will leave you equally impressed.

If you are using KLEI speaker cables - adding these new bananas will be the icing on their cake.

Still Impressed? - yes I am very impressed :-)

Cheers

@toddverrone - I would be very interested to hear how the KLEI™Classic Harmony Banana Connector/Adapter performs on the bi-wire Helix cables you built - they should sound very good :-)

Any intention of upgrading? :-)

Are your bi-wires two sets of cables or joined at the amp end?

If so, the stack feature of the new bananas would be very useful.

Or you could save some money and take advantage of their 12 pack, which I believe is specifically designed to address bi-wire cables that are joined at the amp
