Almarg is probably right. It's your pre/amp combo mismatch causing this. If you, demo a good integrated to see how much it helps. I can tell you the NAD C390 has fantastic bass and a built in DAC.
If your amp is plugged in your power conditioner, try plugging it direct into the wall socket. The silver streak may also be adding brightness. Test that out by substituting some PBJ cables or similar all copper.
Set up your equipment properly -- buy Jim Smith's Book. Your speaker set up is critical and time consuming.
Learn how to use your speakers, how to place them. A couple of bass traps on your room corner should help.
