The Monoprice site has some nice detailed Audio Precision test reports, although not quite as thorough as Amirs. Also this site has detailed reports of the NC502MP multichannel amp provided by Buckeye. Since they both use they same modules similarily configured, my guess is they would measure about the same.
Last month Monoprice had the 8250 on sale so i pulled the trigger. I also pulled the trigger on the Parasound A52+ (a five channel amp) which was also on sale. Compared the two for a month. Both had oodles of ultraclean power, that I believe would meet almost anybody's requirements. I ended up returning the Parasound because size and weight (at 62 its getting hard to move heavy amps and speakers around) and the fact that the 8250 has eight channels (although I am currently only using five).
One note on the 8250. As discussed on the last few pages of this thread, with speakers connected and no input cables installed, I was getting a very slight hum/hiss in the even number channels. Speakers are 88dB sensitivity KEF IQ7 speakers. I had to place my ears close to the speakers to hear this. Once I connected XLR cables between my pre/pro and the amp the noise disappeared. I have not opened the case of the amp to see if Monoprice added their shield (see post#282) to eliminate/reduce noise. This is nitpicking but If you are concerned about this and are using very high sensitivity speakers and RCA/XLR adapters you might want to consider alternatives.
Note two and this is my theory and I have no facts to back this up.
@mhardy6647 mentioned the fix in post #282 looks like a shield. I agree. The shield separates the power supply from the input signal that arrives via a 16 connection ribbon cable. It seems to me noise from power supply components are finding their way into the ribbon cable and finding their way to the amplifier output at a very low level. Balanced XLR cables will cancel this noise out where an unbalanced cable wont. I'm not sure why Hypex would use a ribbon cable in lieu of shielded cable or twisted pair, but it is what it is and i dont think this should be an issue for most users.
Anyway, small imperfections aside this is a great amplifier and I can eagerly recommend the NCXXXMP based amplifiers available from the various manufacturers.
