Bi-amping LSi15s with a six channel amp?
Hey guys, I am thinking of making a change in my system, and I need your help.
I have an Emotiva LPA-1 driving LSi15s, an LSiC, and four LC65i in walls. I am using an Emotiva LMC-1 processor, and am pondering going back to a Pioneer Elite AVR (probably a 92TXH) as a preamp.... I really want lossless audio from my PS3 and Tosh XA2 both. There is a rumored firmware update that will allow the XA2 to pass bitstream DTS-HD Master Audio in the near future...
Anyways, back to my question.
I plan to keep the LPA-1, and use it just for my front three speakers, then use the Elite AVR to run the four surrounds. The LPA-1 does about 225 watts into six channels at 4 ohms. The rear channel can be split and used as a 6th and 7th channel at a lower output, which is how it is now.
I would like to run all six 225 watt amps to my front three speakers. To do so, I would remove the jumpers on the front three speakers and run a seperate amp channel to each set of inputs.
This is bi-amping, correct? I have heard some say that if you bi-amp using the same power supply, there is no benefit. I have also heard it said that sending individual amp channel's power to each set of inputs does yield great benefits.
What are all of your thoughts? Do I see a benefit here, in my case?
Thanks all!

That is bi-amping, you are correct.
Benefits, it all depends on the amp design. Try it out. I bi-amp with my 5ch amp but I can't say if it makes a difference or not. Like you (would have), I have an AVR that can drive LSi's so I have nothing to lose by letting the AVR handle surrounds, otherwise I'd just let the amp run surrounds instead of bi-amping. -
Interesting, some say that they can hear a significant difference, some none really at all. It will be very difficult to get a good A/B comparison. In order to try it, I will have to put in and take out jumpers, etc..."People sleep peaceably in their beds at night only because rough men stand ready to do violence on their behalf." George Orwell

I would use stacking bananas at the amp for instant changes, simply swap them at the amp.
