As a current S/L M1 owner, I'm interested in the results of your auditioning.
As downsizing is probably in our not too distant future, SET amps & Duke's speakers are appealing especially when they're compared to the 200 lb. ea. CAT monoblocks & M1's that I presently own.
So, if you think of it, or have the inclination, I would love to hear of your findings.
Cheers,
