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.

Tom.

Not a bad idea, Slipknot. With any luck, I will be able to install two new 20A lines, in addition to the shared circuit that is already there. Between these three circuits, I should be able to adequately divvy everything up. It sounds like I will want to get one or two high current UO's, and at least one Juice Bar. After talking to customer support from PS Audio, I will probably be pulling the ACE-515 from my audio system entirely. Now, my only problem will be remote on/off control, since in my setup, the Juice Bar(s) will probably be at the back of my cabinet, and not easily accessable. One option may be to see if my electrician can build me two "Juice Bar-like" boxes, with remote on/off switches for each. I would think that if he uses quality components (probably Power Ports), star-wired, with good attention to detail on the construction side, I should be able to get a decent product.

My one remaining question would be whether or not I need a Power Port or two on the wall, or if decent quality receptacles would be adequate.

Thanks again, Tom.

My favorite outlets have been those supplied for us by AudiogoN member Albert Porter. His "Porter Ports" are cryo version Hubbells. Albert is one of the most well-informed and helpful folks around. On a couple of occassions, he has arranged a group purchase for members. I don't know if he has any extras available from the last round. You may want to contact him privately and inquire. They are the best outlet I personally have ever used. Some folks have even swapped out the PS Power Ports in their Ultimate Outlets for Albert's "Porter Ports".

Sounds promising. I will look Albert up.

Thanks again, Tom.

Well, after talking extensively with my local dealer and with Albert Porter, I am going to pick up three UO's (two regular and one 20 amp high current) for my three circuits (two dedicated) that will power my stereo/HT system. On the two regular UO's, I will be installing Porter Ports. I will also throw Porter Ports on the wall outlets for all three circuits, and I am picking up an extra one to use when I add a powered sub. Instead of a Juice Bar, I am going to have an electrician friend of mine build me two double gang breakout boxes (using Porter Ports, of course!). So, that's a total of 10 Porter Ports! Based upon all the glowing reviews by AudiogoN members, I decided they were worth investing in. Now, my only issue remains turning everything on and off with one or two switches. My electrician has recommended that I use wall switches to turn off my dedicated circuits (one for preamp/source and one for amps), which may actually be a killer idea.

Thanks for all the input, especially from Slipknot!

Take care, Tom.

Hi guys- Just my two cents. Victor Khomenko, the head BATman at BAT, in addition to most other high-end amplifier designers, states that "a single dedicated power circuit will usually produce the best result". As far as our systems go, any difference in ground potential (due to multiple circuits, conditioners, etc.) is seen as a signal, which will amplified, and added, to the real signal. Our ears should be the best test but a good high-resolution system will almost always prove the BATman right.
