When an amp puts out 90 watts....


into 16, 8, or 4 ohms, what does that tell me about the amp? I am use to seeing an amp's output increase, sometimes even doubling, when going from say 8 ohms into 4 ohms.

The amp in question is the Copland CTA 506.

Not only is consistent power output typical of tube amps, but also McIntosh amps that use autoformers have a stable power into all impedences.
