I was consiering to get dual UPA-7's to bire wire my entire setup but i've decided to use FXi3s for the four surrounds in place of the RTi4s i originally planned. The FXi3's are not bi-amp capable. With that in mind, only the front 3 mains (RTi10 and CSi5) will be biamped.
Would i be better off getting a UPA-7 AND an XPA-3? The UPA-7 would power the highs in the front 3 speakers and the full range of the 4 surrounds. The XPA-3 would be used to power the lows on the front 3 speakers.
My understanding is that the XPA line is of better quality and more powerful so I figured I would be better off using a higher quality amp of the same price for this bi-amp project.
Is it bad to mix-and-match two amps from different lines?
