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.

The answer to your question of the Adcom getting hot is no, it does not get that hot at all. Something is wring with yours. Call them, you can get the # from their web site and ask for tech. support, they are very helpful.

I have a high current UO for my mono amps on a dedicated line, and another standard UO for my source components on a line, and the surge issues being dealt with at the service panel.

Excellent advice! I have consulted with my electrician, and with a little playing around, I am able to come up with two free 20 amp circuits to use for my home audio system. I am now going to order two UO's. Any thoughts on where to get them from? Also, what brand/type whole house surge unit did you use?

Thanks, Tom.

Tom,
That was my response to your thread. The PS Audio Ultimate Outlets are readily available from a number of online retailers new, but, in an effort to support the sellers here at the 'GoN, there are always both high current and standard versions for sale here at very reasonable prices. Good luck!

Make sure you can return the UOs if you don't like them. I bought a 20A one from Audio Advisor a while back and returned it because it limited the dynamics of my Rowland Model 10. The Rowland sounds best plugged directly into the wall.

Sorry for not crediting you with that quote. I did know it was you. And thanks again for the good advice! Also, great point about sticking with Audiogon sellers. This is, indeed, a great resource, and I'd like to see its supporters continue to thrive.

Good point about finding a dealer with a return policy. From what I have read about the UO's, it seems very strange that they would have a detrimental effect upon your system. Any idea what it was about the UO that caused the dynamics issue?

Later, Tom.
