    Does anyone know if the SM-400 puts out 400 watts into 8 ohms? Like if I was using it with a 500 watt Goliath II (an 8 ohm cab), would that be sufficient power? I know the 400s would be better, but I can get a 400 for pretty cheap.

    I don't think that the SM400 will put 400 watts into an 8ohm cabinet. I think it will put 400watts into a 4ohm cabinet if both channels are bridged. That having been said, I think the SM400 would be a good sounding match for the Goliath II unless you will be regularly playing at very high volume levels.

    Never mind - I answered my own question. It does put 400 watts into 8 ohms and 420 into 4. So I guess the only difference between the 400 and the 400s is what it puts into 4 and 2 ohms, and that the s has a fan. Does that seem right? Also, what does everyone think about using it with a 250 watt 4x8 cab. Obviously 140 watts from the stereo output is too little, but is 400 too much?

    Actually, the S model puts out 500 watts bridged at 4 ohms. It also has a presence control, and a variable output on the DI, as well as a ground lift on the DI. Both amps are the same power at other specs, IIRC. I own one of each and they get plenty of volume and bottom from my Goliath II cab.
