I currently have a Marantz SR6006 driving a Polk RTi front soundstage. It sounds good, but after hearing someone's similar setup with a Citation pre/pro system i can seriously hear the lack of clarity from being underpowered. I can in no way afford the Citation Amp (cheapest i could find it for used was over $2200) so I am looking for alternatives. I looked at the Emotiva XPA-3 and am leaning towards that. My questions are:
1) Are there any alternatives I should consider in the same price range?
2) Will using my AVR as a pre while still having it power my rears present any issues? In other words, am I correct in assuming that my AVR CAN be used as the pre?
