I have to agree with the first two posts. You might want to try some different interconnects. The P-5 appears to be the strongest part of your system right now, and you might have to play around a bit to get the sound you like. Try a good balanced XLR cable between the P-5 and Bryston (assuming it has XLR inputs) and maybe take out that Kimber cable, at least to try some other interconnects. Also, you might want to try borrowing a decent power cord from someone to try on your SACD player. Sometime they can tame the too-crisp highs.
Good luck,
Derek
