I thought I had a bright system too. I bought PAD Musaeus speaker cables and an interconnect for the CD player and it helped more than any other cable I tried, but the system was still brighter than I preferred.
When I finally tried the Musaeus interconnect between the AMP and Preamp though, the difference was night and day. Now I have a deep sonorous tonal balance that sounds right all across the spectrum.
From my experience the best thing you can do to kill system brightness is to add a darker sounding cable between the pre and the amp. The two that worked wonders for me were the Pure Audio Musaeus and the Acoustic Zen Matrix II.
As always, the more transparent your system the bigger impact on sound your cables will make.
