I wonder if some of the above responders have used a DR-3. Not trying to start any argument, but the power rating of that amp is very deceptive. It wasn't really rated that low due to current limits or voltage limits. But because of thermal limits. Being a class A design it could get too hot at continuous full power levels. But it had lots of headroom. It could punch out plenty of power and current on musical signals. More than 200 watts with 8 ohm speakers. And yes it doubled the output down to at least 2 ohms. It has the same approximate muscle as your basic 200 watt amp and sounded like it did. It had a bit lightweight low end compared to most other SS amps. It therefore matches up best with speakers that are warm sounding. An excellent match, one of those magical matches really, is a Mirage M3si. That is a full, warm balanced full range speaker that works better with some muscle behind it. The DR-3 just plain makes music and power is plentiful for M3si's.
