I ordered the Sherbourn 7/2100A. It should be able to put out a butt-load of power. It requires two outlets (or a single 20A), and it has a bunch of extra tricks up its sleeve as well like Load Detection etc.

Take a peek!

I haven't heard a bad thing about it!

Just my two bits!

Looks interesting, but I am wating to see what the 7900 amp from the Outlaws will provide. It should be out this year sometime.

i too, have been waiting for the 7900.

The Carver Sunfire Cinema Grand Signature 400~seven claims to produce 400w per channel continuous all channels driven on a single 15a breaker. But the fuse in the Carver still blows at 1800w. What does this mean?

That their physics textbooks use different equations than the ones that the rest of us use? That does seem pretty improbably to me - 2800W of output from a 15A 120V circuit (1800W) doesn't make sense to me.

I am using a Sampson SX2800 for my two passive subwoofers and noticed that it also uses a 15A breaker. There was also a note in the manual: NOTE: If you are operating the SX amplifier at high power levels for long durations in fixed installations,
you may consider switching the operating voltage to 220 volts. A licensed and insured electrician and/or
technician should perform this modification.

I didn't know I could switch my power circuit over to 220V and use the same 120V amplifier in a 220V circuit. Is that possible?

Your house service is typically 120V/208V - some appliances use 208V connections. It's a different receptacle than 120V, though. I'd be curious to hear what one of our electrician or EE residents had to say about that (feeding a 220V power supply with 208V, cord & plug issues, and the like), but I'd probably leave mine 120V.

Some devices have power supplies that can be set for 120/240 and some (usually smaller) devices have power supplies that can work with a wide range of input voltages. For instance, the adapter for this notebook PC works 50-60 Hz, 100-240 volts AC.

So you need to consult you owners manual on what voltages are acceptable for the device and how to configure it.

Converting a recepticle over to 240 isn't a big thing usually, but as Gonk says, there are different blade configurations for the recpticles and plugs for different voltage and current ratings.

After all that, we listen to music, so in reality it's probably a waste of time for anyone using their amps for listening rather than as a heater.

But it is an odd spec, for sure.
