I recently purchased an RSP-2 and XPA-2, driving a pair of Magnepan 1.6QRs. I have not done any A-B comparisons with other amplifiers, so my opinion may be of somewhat limited utility. However, I am more than somewhat pleased with it. The 250 wpc XPA-2 drives the maggies beautifully, really bringing out the base in a very controlled way. To my ear at least, these do not do anything wrong. The phone stage on the RSP-2 seems to work particularly well with my Rega p3/24 and Dynavector 10x5 cart.
Also, Emotiva's customer sevrice is great and their return policy allows you to buy without much risk.
Yeah, I've kind of drunk the blue cool-aid.
