NAD Masters Series M22 power amplifier

In the January 2015 edition of "Music in the Round," I reviewed NAD's latest Masters Series preamplifier-processor and multichannel power amplifier, respectively the M17 ($5499) and M27 ($3999). I was taken with both, but the M27 made a special impression. In many ways, it personified what a modern power amp should be: quiet, transparent, cool running, and compact. Its neat package of seven 180W channels inspired me to consider that stereo or mono versions of such a thing could supplant the ungainly monster amps I was using in my main system. So I asked NAD to send me not just one but two samples of their new two-channel power amplifier, the Masters Series M22 ($2999): Although this is a review of a stereo amplifier, I did want to have my front three speakers identically voiced.
