Incidentally, I bought a Micromega M-1 from Underwood last November as the new centerpiece of a secondary office system with older B&W CDM7-NT speakers and an old Sony CD changer. I've been quite pleased with the Micromega so far.
The dealer, while quite positive about the amp in general, was dubious that the streaming would work. Indeed, the Micromega IOS app is entirely non-functional. But for my purposes, it simply doesn't matter -- I ran a $10 LAN cable from my IMAC desktop directly to the Micromega, and I'm listening to Qobuz, controlled by my desktop, as I type this.
