Atmasphere amps trustable?

Were they having, uh, group delay?

I have some Atmasphere Novacrons mated with Classic Audio 3.3 speakers in a 20X18 room that just sound fabulous. Very reliable 

I built a pair of M60s 20 years ago and they're still going strong.  I did send them back to Ralph for an upgrade and to check them out a couple years ago.  I highly recommend them--rock solid performance.

P.S. Atmaspheres do like a higher speaker impedance--I use Paul Speltz Zero autoformers as speaker wires, which bring the impedance of my Kef Reference 207/2s up to a respectable ~8 Ohm minimum and 14 Ohm avg which increases the output of the amps up into the 70W range.

Wait…can't I simply get a screwdriver and remove the transformers from my amps? And where do all the unused transformers go? Is there a pile somewhere? Is there an opposite amp that is ALL transformers? These are the sort of sophisticated questions that need to be asked…impedance imschmedance!
