Dear all, I have a Cyrus 8vs2 which I am using to drive the tweeters with a Cyrus X Power connected to the bass driver. The CDP is the Cyrus CD8SE & the speakers are PMC FB1+, the CDP & both amps have PSX-R power supplys. My questions are regarding the new 8XPd / 8XPd Qx - would I gain a significant improvement? (if yes where; bass, mid, treble, soundstage, control, etc), also the 'Qx' part of the 8XPd Qx - would this give any benifit?
