Cable Upgrade: Too much transparency

I agree some more burn in time maybe needed (assuming they are new cables)...like a few weeks. Also most cable are directional (assume you know this...)

Also, are you sure you have your speakers set up right? What about room treatments?

Just a few thoughts...

While the GFA 545 II has great weight and punch in the lows, its top end can be forward and unrefined. Not sure which cables you had in the system before, but by adding the more transparent cables you may have exposed this weakness that was otherwise being hidden or compensated for.

I have never found the Diamondback to be a particularly transparent cable.

Thanks very much. The cables were burned in before I bought them. Is there a better interconnect for this system? I had Monster Cable that was about 20 years old. The only thing I changed was the cable. I'm sure room treatments and better speaker positioning would improve the system but I'm constrained because it's in my office.

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.
