I copied this from another thread so share
I have the emo xpa5 and mmmc1 powering my axiom setup and must say they are excellent! the build quality is great. Music has never sounded so good. when emo releases the xmc1 processer, dual subs, and the cd player you can bet they will all be in my theater! Plus everything comes with a 5 year warranty just like axiom
If you are worried about the quality of emo products here is a quote from audioholics on their new surroud speakers:
Right from the beginning, I suspected that Emotiva had something special with their ERD-1 dipole speakers. The Axiom QS8's are a very highly regarded rear "quad" pole speaker (a top and bottom woofer and two side angled tweeters - one on each side all firing in phase). I was surprised to find that the ERD-1s bested the Axioms on almost every metric I could come up with. The opening sequence of the first and title track features a keyboard bouncing around the rears and what sounds to be a train pulling into a station. The ERDs really performed well not only during the quiet section at the very beginning but also in remaining articulate during the louder sections. At no point did I think the ERDs were being overpowered or drowned out. At the same time, they blended well with the rest of the system. Basically, when I wanted to hear them I could, when I didn't, they just disappeared. While some might say that a bipole configuration would be best for multichannel music, I found the dipole setting to create a nice diffuse sound that still performed well for point-source effects. As always, we encourage you to experiment for yourself and see what you prefer. Just make sure to check your levels as you switch between the settings as the levels are likely to change. While I've always found the Axioms to be a fine surround speaker, the ERDs are in an entirely different class
