I am using pass amp x150, with preamp x2.0 and the speakers are thiel cs2.3 when i turn on the amp I heard very loud noice in the speaker tweeter, the volume on preamp is on minimum and the source is not even turn on, all the cables are corectly hooked up
Sounds like the power switch on the amp isn't buffered. Since it's a class A design, I suggest you consider leaving it on all the time. It might sound better that way, too. Good luck.
