A lot of good suggestions already of course. I would suggest you consider swapping out the stock tubes anyway! There have been a rash of great 6922s posted recently at great prices (I saw several noteworthy posts today alone). Tube rolling can give your system TREMENDOUS gains.
Incidentally, repowering can cause problems. That having been said, I am surprised if the change in sound is symmetrical, though, given your description. The only time I've seen that resulted from bad power (work system - sub-fuse blow but took out four telefunkens and led to an immediate PS Audio purchase for my work system). Have you double-checked phase and connections? Any change in sound at different times of day (i.e. power issues)?
Have fun,
Jacob
