Bi-amping LPA

[rnatalli]

I know that by using the same amp, it may or may not make any difference. But since I have some spare speaker wire, interconnects, banana plugs, and amp channels available, I figure why not bi-amp (or whatever you call what I'm doing) my mains. Here's the plan:

Y-cable to split outputs from the preamp. I have spare y-cables that have 2 males and one female. I assume it doesn't matter if I have one wire from the preamp that then splits at the amp. These are 3' foot cables.

Channels 1 & 2 = Left
Channel 3 = Center
Channels 4 & 5 = Right
Channels 6 & 7 = Left and right surrounds (Nothing connected to these as I'm only running 3.1, but that may or may not change in the future)

I'm not using channels 6 & 7 to bi-amp the mains since they have a different power rating and are +/- 3db I believe. I believe I'm on the right track, but want to be sure. Thanks!

Biamping

Unlike a receiver, your LPA-1 amp can deliver its full rated power into each of its channels so you will have a greater benefit with biamping. This is still considered passive biamping, however. Active biamping requires an external crossover.

You are on the right track with the Y cable from one of the pre-amp outputs to two of the amp channels. Try it out and report back.

Considering that I just went from 100 watts/ch to 14 watts/ch with no loss in any area of SQ and gains in some areas, I am highly sceptical of the value of more power, regardless of how it is obtained.

Okay, my understanding is sound then. I'll report back most likely this weekend when I have time to actually do it.

I had some time today so I went ahead and gave this a shot. I can't really tell any difference. I guess it really depends on the speakers. I might try switching back a few weeks from now and see if I notice a dip in SQ. For now, I'll leave it this way as it doesn't appear to be doing any harm and for all I know, there may be a performance gain when I crank the volume up
