The price of the M250 is 7500. Smaller versions are available in the form of the M180 at 160W per channel and 5750, and the ST150 at 150W per channel at 4350. Also featured above is the ST70, which has been around for a while now, and is highly recommended by myself. This stereo amp supplies a healthy 70W per channel, driving my own Martin Logan Aerius to very high volumes for 2150, which is not unreasonable. It's very solidly built and appears to be available with either chrome or black chassis.
Sound quality is very good, too.
The M120 on the other hand, at 3500 and 120W per monoblock, maybe OK in some systems, but I've yet to hear it one I've liked. The Stratosphere ST1 turntable was also present in a finish I hadn't yet seen. The Graham arm and Transfiguration cartridge appear to be the order of the day for those with the money. Suspended on airpods, which must surely be the ultimate in mechanical isolation, it looked absolutely superb. Two's, plus all the other goodies like SME Series V, Koestu, Iso, Hera etc.
