Emotiva amplifiers review/experience?

I have had 2 UPA-1 monoblocks and the USP 1 preamp for a year and half now and they all work fine, in fact I use them with my vintage Original Advents in the TV room and these speakers have never sounded better. As for build quality, they do have a 5 year transferable warranty and although I haven't had to use mine, from what I've read Emotiva seems to be very responsive on warranty issues. I would imagine that with that long (and transferable) warranty they would want to keep their costs low by doing some reasonable QC and build quality

Josh358, on the question of longevity, other than electrolytic capacitors requiring replacement as they age (and I have some Marantz amps that are 40 years old that still sound fine to me even though they have not had a complete recap) the real question to me is whether the Emotiva designs have any proprietary unobtanium chips (for protection circuits for example) that if they fail say 10 -20 years from now, you are SOL. On the other hand, answering my own question, the amps are inexpensive enough that if they fail 10-20 years from now so what?

I think the UPA 1's are very fine amplifiers (Think about it, $600 for two monoblocks - 350 watts 4 ohms) and they do sound very very good with my Magneplanar MG 1 imp. As good as my Conrad Johnson MF 2300 A amp? ( $3,500 new) no, not quite as warm and musical but get real will ya? The Emotiva is easily 85% of the CJ sound.
