I own a Classe 70 and probably will try to find a DR-9 or DR-3 to upgrade to sometime. I have noticed that my amp is really sensitive to the power from the outlet. It is picky about powercords, is susceptible to hum and sounds much better at night. Classe amps are good for driving low impedance, insensitive speakers and are smoother sounding than a lot of other SS amps. Auditioning my speakers at a dealer I listened to a Classe 300, an NAD silverline amp, and a pair of tall Levinson monoblocks. I much preferred the Classe. NAD was too bleached out, Levinson was decent, but boring.
