Love mine! I'm kind of like Mike Mercer when it comes to Peters cables. I just exude enthusiasm for them! I own DHC Complement 3 Cu/Ag hybrid, the Complement 4 Cu and most recently the Complement 4 Ag. The Complement 4 Ag is the best cable, by a significant margin, that I've had on my TH900's. I've had the stock cable, the Stefan Audio Art Endorphin, the Comp 3 hybrid, the Comp 4 Cu and now the Comp 4 Ag. It just brings out more detail and has a better portrayal of timbre. Because of those two improvements it seems to present a very realistic soundstage.
I've been to quite a few live performances at Ruth Eckerd Hall in Clearwater FL. It is a very well regarded venue for being acoustically accurate. I've seen performances by Jeff Golub, who unfortunately passed this January, Boney James, Dave Koz, Mindi Abair, Richard Elliot, Rick Braun, Bryan Adams, Creed, Daughtry, G3 and Joe Satriani concerts there, just to name a few, and use those as reference. The Comp 4 comes the closest to portraying what I heard live. We all know our aural memory is limited so take that for what it's worth but I seem to be more emotionally involved with the music using the Comp 4.
