McIntosh amps are actually classified as A/AB since the first few watts are in class A mode. This is more than enough power for Klipsch speakers.

Please provide a source for your info. Believe your are incorrect. No McIntosh power amp I am aware of has the required "sliding bias" required to operate in Class A at any level, but I'm happy to be proved wrong.

Class AB biased amps generally operate in Class A for some portion of their output depending upon their level of bias. For most AB designs the amount of Class A power is very small but with a higher level of bias current they can be designed to provide a higher level of Class A power. This does not require a sliding or tracking bias arrangement, but is just operating Class A within the limits of its fixed bias level. At higher power outputs such fixed bias amps operate in Class AB.

what is the lowest dip in impedance on RF7mk3? RF7mk2 was measured to 3,7 on approx 160hz as the lowest.. Ask because im about to bridge two amplifiers that recommend only speakers with nominal 8ohm rating...

Bradley and Geoff, Thank you for the great info, I think that was the final nudge I needed. I too have those 24 k metallica cd's "masters" and "ride the lightning". Thank you for the post. Oh, one question, are you running a sub with the rf lll's for 2 channel? Let me know. Thanks
