Only if you try to feed them test tones, have very small sub woofers with a lot of equalization, or the amps are biased for enough class-A output that they're doubling as a space heater in which case the extra air-conditioning will be a bigger problem.

For the last three years I had my home theater setup prior to moving I ran a half dozen amplifiers (7.1 with actively tri-amplified front speakers) placarded at 5760 Watts maximum off a single circuit along with 675W of recessed lighting.

It never popped a breaker because the amplifiers were generally loafing along at under 200W total (although reference level home theater can get loud, there's enormous dynamic range and the average isn't even a Watt).

To me, an important consideration is the question: What is the best use of your available funds? I suspect that investing in multiple amplifiers isn't.

Given the processor you are using, I would say that a good multichannel amplifier would be the better choice. I am familiar with multichannel amplifiers from Anthem and Parasound. Both make excellent products.

I agree with Summitav that, if you want to get the most out of music, you might consider purchasing a higher quality 2 channel amplifier for the FR and FL channels, and then a more affordable 3 channel amplifier for the center and surrounds. My own system has a version of this approach.

Good luck.

Bryoncunningham. I have a Parasound HCA 2205AT and want to upgrade. My parasound runs fairly hot(common for parasound).

I am looking into Wyred 4 Sound so I can get a mono modular amp. Say 3 dual monos + 1 mono, 3 channel and a 4 channel.etc. What are your thoughts on this brand and what else would you suggest?

I do think running seperate mono channels will have better seperation, dynamics, imaging and soundstage.

My pre processor is a Onkyo Pro SC885.

Hi Bacardi - I have no direct experience with Wyred 4 Sound, so I can't offer you an opinion. Sorry.

I can certainly see the appeal in multiple mono amps. But I agree with Summitav's comment that...

Unless you are going to be building the SOA $40k multichannel music sound system, there is no need to use all monoblocs.

That is why I suggested a middle ground approach of 2 amplifiers: a higher quality one for the FR/FL, and a more affordable one for the center and surrounds.

I do think running seperate mono channels will have better seperation, dynamics, imaging and soundstage.

There is some truth to this, provided you are comparing amps of similar price/quality. Keep in mind, though, that some of the best amplifiers available at any price are stereo, not mono. In other words, amps that have channels sharing a single power supply and chassis are not always inferior to those that don't. It comes down to the particulars of the design.

With that in mind, I will reiterate that there are truly excellent multichannel amps available. Two that come to mind that I have direct experience with: The Anthem Statement P5 and the Parasound Halo A51. They are powerhouses with excellent sound quality. If they are out of your price range, you could consider the Anthem Statement A5 or Parasound Halo A52.

Three notable differences between these Anthem and Parasound amps that may be relevant to you, given your comments:

1. The Anthem Statement amps use multiple power supplies (2 power supplies in the A5; 5 power supplies in the P5). The Parasound Halo amps use a single power supply.

2. The Parasound Halo amps are class A for the first few watts. The Anthem Statement amps are not.

3. The Anthem Statement amps run much cooler (because of 2).

I have owned amps from both manufacturers and liked them both.
