I have been given $1300 to do as I please and I have been looking at an Emotiva XPA-5 with with an onkyo tx-nr709. My setup consists of a HK AVR-525, Rf-52, Rc-52, icon vs-14, ss.5, and an Rw-10d. My main couple of questions are one, is the xpa to much amp and not practical considering how efficiant the speakers are. Two, is their another alternative people reconmend for an amp/pre-amp?
