I've the predesessor, the AQ coral. A nice cable with a friendly sound, probably because AQ uses solid core copper cables which gives an 'analoque' sound, with very slightly rolled off treble and and loose bass.
But the cables do age over the years, especially if you bend it to much (solid core ccables do that).
And the soundstage (on a speakerbased system) is small.
Replacing my coral with a DIY Kimber PBJ/bullet plugs ,was like a breeze of fresh wind, soundstage expanded to the room bounderies, bass got tighter en more details came through, without articial highlighting.
But of course it all depends on taste and system, and I can very well imagine the AQ being the perfect addition to many systems, especially if they might tend to fatigue and need some taming.
