I just thought I would post an email correspondence i had with someone on audiogon, who was selling the grover UR's and i missed out, but i asked him why he was selling in the first place and what his impressions were - obviously, this is his opinion on his rig so take it as such, but i thought it would be nice to post a contrary insight to what has already been said:
"I initially liked them but thought they lacked a bit of warmth. Still, I preferred them to the first generation Acoustic Zen Matrix Reference and Silver Ref ICs and Satori speaker cables I had on hand. Longer term I also came to feel that the Grovers accentuated the leading edge of transients unacceptably. I replaced the ICs with a pair of Von Gaylord Chinchillas and the speaker cables with Audience au24 or Eichmann Express 6 (still undecided on those), all of which are copper rather than silver, and much more expensive. Results were similar in my two channel rig (Avantgarde Duos, tubed Sony SACD player, Avantgarde amp) and my much humbler hometheater set-up (Yamaha receiver, Kef speakers)."
Again, this is just a contrary opinion posted just to provide some balance and to encourage some feedback on this user's impressions as well as to encourage some healthy discussion on this cable
