Help -- my system is too bright

What preamp do you use with the new Krell amp? Was your old amp Krell also?

Is the new Krell amp fully broken in?, ie how new is it? I've used Syn Res Master couplers to tame a bit of brightness, and also Syn Res Sig. #10 spkr cables are a warm sounding cable that I like. Good Luck. Craig

I appreciate the interesting feedback.

The old amp was an anthem MCA-50, which I still use
for the Center and Surrounds. It was a nice mellow amp, but not as detailed or extended as the Krell. I bought the Krell used, so I'm assuming it was broken in by the previous owner, but it may need more break-
in time. I am using a Proceed AVP2 pre-amp and a Yamaha s2300 Universal Player.

Does "digital hash" or noisy AC cause high end brightness?

Your system may now be so good that it's revealing how many bad recordings there are. After all, that is your system's "job-1". It's amusing when someone suggest using this-or-that tweek to make the sound "warmer" or whatever.
If a recording sounds bad either accept it or find a better one.

The Yamaha is not a good choice with the Krell, It is, as all universal players are: A little to universal sounding and your Krell can reveal poor upstream source with ease. I have two Krell amps and went through the same thing.
