Adding a XDacv3, PSU, X10 combo to my system really extended and tightened up the bass. Not a subtle change. The mid bass firmed up giving a warmer 3d image. This combo would fall within your budget and match your other MF equipment. HOWEVER, I'm finding that this combo aslo diminshes the attack of the upper notes. Less sparkle in the highs. See my vitual system. Just my two cents.
