One thing to keep in mind is there are simply way more of these out there now compared to the year or two following the release of v1. I'm not disagreeing, just pointing that out. Another thing I noticed is that a lot of people commented about v1 running hot/very warm, where as my v2.1 barely gets warm after playing for several hours at moderate volume.
Yep mine got warm always also..but worked brillantly..and i. Agree..more people bought the mstage now..but still..
ps about tamaudio..its the real deal..i boight my opa627 class a module from them..perfect!
