check out audio metallurgy.
the ga-0s are quite lovely. I was using audioquest, diamondback to start and then columbia's. they were nice but the audio metallurgy's kinda destroyed the audioquests. They're beautiful and on audiogon you can get them for an amazing deal, every week they auction off a few pairs in a few different lengths and since it's an auction put on by the manufacturer you get a 30 day trial. In the end I found they simply opened things up, there was more music to be heard then the audioquests could present and the ga-0's could.
working with a wavelength audio brick, music hall MMF 2.2 (soon to upgrade to a clearaudio champion w/unify arm), clearaudio basic phono, denon pma2000ivr (waiting on a headamp GS-1) and akg k701's getting RAL rewire (hopefully will arrive(soon)), dahlquist dqm9c (getting woofers on dqm9's rebuilt)
