I just got a Yamaha RX-A820 AV receiver (100w/ch into 2 channels). So far, very happy with the functionality, but driving my Paradigm Studio 100v4 mains it seems a little under powered. As I have been researching my options this site lead me to Emotiva as good, competitively priced amps. Cost is an issue so instead of buying the XPA-3 (200w/ch) at $629 I started thinking about the UPA-200 (125w/ch) at $314.
If a single UPA-200 wasn't enough for both speakers, I could add a second UPA-200 and then bi-amp the Studio 100s. I understand that this is passive bi-amping, but that would provide each speaker with 250 total w/ch (with some power probably wasted and not needed on the midrange/tweeter).
My center channel is powered so no amplification is needed. The third channel of the XPA-3 would be unused but left for when my Active CC center speaker dies and gets replaced.
1) Would a single UPA-200 be enough to sufficiently power the Paradigm Studio 100's with movies (60%) and music (40%) (living room is around 15'x18')?
2) Would the option of adding a second UPA-200 later using bi-amping be a decent way to try a single first but be able to incrementally add power if needed?
