Blanket statements pro and con miss more relevant points, such as "not all Mc is created equal". Their legacy tube designs are beautifully made, and typically warm (someone said "wet blanket") :-) Its rarely state of the art, but it is solid, backed by a solid company, etc.
Some of their newer designs, including the SS ones and hybrids, are, IMO, quite inferior. for DACs, well, its not their thing (again IMO, YMMV).
All products are trade-offs.
