I have some audio interconnects. From my experience they exhibit a very natural and neutral sound perhaps on the smooth side making treble less of a sparkle.
I can't give a full blown review of them even tho' I've had them for a while simply because the sound achieved through the speakers is very similiar to other cables I use.
These being Nordost Red Dawn.
I bought them as an experiment and the jury is still out as to whether there worth the money. I can say there's nothing nasty about them so whatever they do they seem to do well.
