Top of the line?

So far I am underwhelmed. Maybe I need a power supply or something. Also I have to turn the gain way up on my preamp. A Pass Labs XP 10 

@alman63  Sorry to hear that. Perhaps @almarg can comment on your system synergy / pairings as only he can. : )

Other than the power supply, anything else that may be a factor from your perspective.

FYI, I paired a SST Son of Ampzilla Mk 2 with a Pass XP-20 without issue.

I didn't anticipate any problems, I put an Aric Audio pre into the system and it can't nearly go loud enough. My system consists of:
Ampzilla 2000 Second Edition amps 
Pass Labs XP 10 preamp
Cyrus Audio CDi disc player 
Legacy Audio Signature SE speakers 
Thank you for your time and input 

First thing Monday I would call EJ or one of the techs at W4S (they own SST) and see if they can help identify the problem.  Since the Ampzilla's have an input sensitivity of only 1 volt and your speakers are over 90 db volume is one thing you shouldn't have a problem with. I would think tube noise with the Aric would be more of a problem.

Thanks a lot for the advice. I will do on Monday
