I'm breaking in Proteus Provectus yea even as I type (about 50 hours), so a final eval is not nearly ready. Amp is VAC Phi 300, speakers, Sophia 3's. First impressions were HUGE soundstage, ease (the whole system breathes without effort) and black background. This cable is pure copper, the IC from Shindo preamp is pure silver. That synergy matters, I sense. I've read that this is a dark cable - but the jury is still out until about 200 hours. That's my only caveat so far. Good luck !
