Hugo1, I had Diamondbacks (called Viper before) a while ago followed by King Cobra (called Python before) to end-up with Acoustic Zen Absolute. King Cobra has similar to Diamondback neutral sound but is more refined and doesn't cost much more. By refined I mean cleaner, smoother sounding. AZ Absolute is way better but for much more money. Your cables need time to settle but being open sounding might expose brightness of your speakers or amp. I had this problem with Diamondback (Viper) and metal dome tweeters in my previous speakers. New, warm (but very transparent) sounding, Hyperions HPS-938 are much better and don't sound bright or forward even on the worst CDs.
Cable Upgrade: Too much transparency
I could use advice about the best interconnect between my amp and preamp. I recently added Audioquest Cv 8 speaker cable and there was a dramatic improvement in clarity. I then added Audioquest Diamondback interconnect between the amp and preamp, and it seemed the harsh (in particular brass instruments in jazz). Did the cable create too much transparency? Will I get used to it and appreciate the clarity eventually? My system: Jm Labs Daline 3.1, Jolida 5t, Adcom GFA 545 II, Moon 100 D, Apple Airport Express. Thanks for any insight.
