To curb a bit of the brighness in your system, you might want to try another pair of interconnects. It appears that your interconnects are silver which from what I understand can lead to a bright sound in some systems.
You might try a used pair of Harmonic Technology Pro Silway Mk II interconnects which combine copper and silver in a single crystal technology. They are very detailed but in my system do not appear to be bright.
A used 1meter pair go for about $175 -$225 on audiogon.com.
If this does not cure your problem or perhaps another interconnect, then you should be able to sell the cables pretty much for what you bought them and then investigate the preamp.
Also, you might consider doing some research on room acoustics. Perhaps your room has a very 'live' sound and therefore bright sounds could tend to be overly bright.
-IMO (whose were you expecting?)
