I have a pair of the waves in my system (CD player to integrated) while charging up the battery supply I used them with the supplied wall wart. It took me only a few notes to realize these cables were something special. They are the most neutral cables I have had the pleasure of having in my system. The soundstage was deep, tall and wide as though the walls of the room could no longer restrain the sound. They were faster then my Valhalla cables, and more musical. The bass was extended lower and more accurate then my FIM Gold's cables. Each note, vocal and passage had more air around them, and hung in space a bit longer.
With a fully charged battery you just get more of these good things.
If I can borrow a couple quotes from another Audiogon member, simon74 from another thread here on Audiogon
A really neutral cable should surely be universal - that's the whole point of it being neutral - it lets you hear how good or bad your system is!
The whole point of the cyberlights is that the same laws of physics that apply to any wire be it twisted, frozen, braided or whatever, don't apply to fiber.
I think we all spent too long tuning our systems with cables
And if we had really neutral ones, we might actually spend the money sensibly on better components.
I think Simon74 nailed it
