OTL Tube Amps-- are they superior to everything?

A recent conversation I had with an Audiogon member got me interested in OTLs. His opinion is that nothing compares to them for clarity, naturalness and superiority in just about every area. The Atmaspheres are the amps he has, and they are purportedly very stable, unlike most other OTL designs, which many can tell you were a living nightmare.

This is ironic, because some mfrs., like McIntosh, actually put output transformers on their better solid state pieces, claiming they provide superior sonics.

What is the truth here?
