Hi there and congrats on your new purchase, The MPS-1 is indeed an awesome and heavy duty but gorgeous piece of gear.
Warning: if you think upgrading your amp sounds good, just add the DMC-1 pre/pro or any other of their pre/pros and you will be blown away. Honestly, my system sounds so good I still cannot believe the sound that comes from my speakers. Really a great value indeed.
Customer service is second to none, how many Presidents of companies pick up the phone and actually engage in a conversation with a customer??? I have had the pleasure of speaking with Dan Laufman (Emo Big Dog) several times myself.
I cannot recommend Emotiva equipment highly enough, they just flat out rock!
As a side note, if you are also looking for really amazing top notch speakers to compliment your Emo gear, another fantastic internet direct company is Axiom. I am lucky enough to own the M80v2( top of the line floorstander) and cannot say how pleased I am with them, its as though they were designed to match the Emo "Big Dogs", this is sonic bliss

I have not heard their center channels but some folks including the reviews here on Audioholics think they are not quite up to par with the rest of their gear. I can say though that the speakers I own(floorstanders) are simply breathtaking for music and HT alike.
Congrats and enjoy!!
