Hi there,
I have a Denon reciever as a preamp & Emotiva LPA-1 happily feeding my M60's and all other speakers and sounds great.Overall Emotiva is a very reliable company, remember that it's mostly problems that get posted on forums more so than customers with no issues.Their failure rate is I believe around 1% which is well below industry standard.Lot's of guys running power hungry speakers there to with no issues.
