Well, the ML2.1 has a very robust output stage. Output power is only one data, the internal design is normally a total different chapter.
Another superior sounding amp is the old Pass Aleph Design, Aleph 0 monos for example. Or, when you prefer the unique superior sound from Lamm amps with more power, a super choice is Lamm 1.2Reference. Most high powered Transistor amps have a real problem to sound good in their first few watts, the M1.2R is linear from scratch up.
And, all of the above are super reliable... :-)
