Using two channel amps as monos?

I'm not familiar with your amps, but are you bridging them to Mono, or using one channel of each in a "stereo-mono" operating mode?

I'm far from an authority on this topic, but I think it depends on the amp. Except for raw power output, many amps don't perform as well bridged (ie, sonically)as as the do un-bridge. Parasound published in some of their user manuals that using them in "stereo-mono" will produce better sonics than when bridged. In addition, because the power supply is only driving one channel, the power output is about 40% higher than rated for 2 channels driven.

I was planning on using the left channel on one and the right channel on the other, so I'm basically using one half of each two channel amp. So I guess your refering to a "stereo mono mode". My hope, since I have two identical two channel amps was in channel separation by using two independant power supplies. I have never tried this, but it seems feasable unless someone knows of any negatives in this approach.

In theory you should gain aeparation with 2 chassis and a little more power/headroom with one power supply for each channel. Will you hear a difference? Try it and let us know.

Only negative might be the unused amp channel not being hooked up to a load. With most SS, the amp doesn't mind but you might check with the manufacturer to be sure.

This works great with Sunfire amps. I've tried it with both the 300s and the Signature 600s. Both are great improvements over using one amp in stereo, and the 600s are far superior to the 300s.

Jeff,

If you're only planning on using the LC on one and the RC on the other, then the main benefit, as Onemug notes, would be better separation.

In one of my systems, two Pathos Classic Ones are running in bridged mode and there is a noticeable difference in separation, sound staging, headroom and bass articulation.

Do a search on the Pathos in bridged mode and you'll likely hit Doug Schroeder's write up about this. Though his focus is on the Pathos, I'd imagine that similar benefits would accrue for amps that can be bridged. If the Edges can't be bridged and your speakers can be bi-amped (i.e., separate tweeter and woofer taps), perhaps you may try vertical bi-amping using one channel of each for the high and low of one speaker.

Cheers,
