Steve Reeve, reviewer for Fine Art, has the following to say about the Classic Harmony Banana:
It took a while to bring the KLEI™Classic Harmony Banana to market but I have to award kudos to Keith Louis, and his team, for taking their time to “get it right”.
The KLEI™Classic Harmony Banana appear 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 last thing you want at the end of your speaker cables!
I highly recommend this product!
