“The Blue Diamond’s refinement addressed vocal clarity, projection and body impressively. Decay of strings and timbre of the acoustic guitar led into spatial awareness including crowd interaction and theatre perspectives. Yet what I found really intriguing was how the clever top end functioned….The point is that the Blue Diamonds relished those fast transients and delivered them with realism and sure-footedness, with that anticipated sharp “crack” delivered rather impressively, equally so with deep articulate bass laden with well defined and executed timbres and textures ..”

“The Green cables could be described as ‘sweet’. That doesn’t mean cloying or that they throw any sort of veil over detail, far from it. These, warm, very friendly cables broaden the sound stage and provide, for the first time, an onion skin array of musical detail. That is, bass exhibited a multi-tonal depth and vocals displayed a complexity unheard by both the Blue and Black cables. …ideal for any slightly bright system”.

“.. The green is a significant step ahead of most cables at the price in terms of communicating those nebulous qualities we think of as musicality and performance…”
