Using AVR as an Amplifier

[bobbydrugar]

Searched but only found threads with the oppisite condition. I am looking in to moving to Seperates. I currently have the Onkyo TX-NR906 (See my Sig) and I have limited power amperage to my apartment. I Know that I couldn't support the Onkyo with its massive amp section and an emotiva UPA 7 at the same time (too much amperage for my circuit). So I was wondering I know its not the best situation but would it be possible and could there be any benifit of purchasing a Preamp Processor for now and connecting the multichannel outs of the preamp to the multichannel in on the onkyo. This would give me a sepeation of the processor components and the AMP section. the onkyo delivers 145 WPC pretty consistantly through the 7 channels. This would tie me over till I could purchase a dedicated AMP like the UPA7 (it will be later next year because I am also looking at a new Plasma TV as Well). Again I am looking to make incremental shifts in my system and was just looking for your thoughts on this.

Thanks,
