Power conditioner for amps

I recently picked up an Adcom ACE-515 (power conditioner with timed switching for pre/source and amp products) from a fellow Audiogon member, and while it seems to work fine, I have noticed that it tends to get quite hot and will trip the circuit breaker if I run my system fairly loud for any period of time (which I do like to do on occasion). For the record, the amps that I am running through this are two GFA-555II's (bridged mono) and a GFA-2535 (which is really two GFA-535's in one chassis).

My concern is that I am running too many amps through the ACE-515. So, I called my dealer about possibly upgrading to a larger unit. But his advice was that I should be running my amps straight out of the wall outlet, and not through any type of conditioner. He said that the ACE-515 was great to use on source and preamp gear, but that it would limit the current getting to my amps and that they would sound better with nothing between them and the wall outlet. I asked him what about spikes, surges, etc. His reply was that amps are not as susceptible to damage from such things, and that I shouldn't worry about it.

What are y'alls thoughts on this topic? Should I just plug my amps straight into the outlet, or should I get a larger power conditioner? I do like the staggered power on, power off that the ACE-515 provides.
