I picked up a pair of LSi25s last week for my two channel system and I'm loving them so far. I'm currently using a NAD C372 integrated amp to power them which is fairly powerful at 150 wpc. I can bypass the preamp on the NAD and just use the amp section so I'm thinking about picking up a Peachtree Audio Nova integrated primarily for the tube preamp stage and the built-in dac. It does happen to have a built-in 80 wpc amp I was just going to bypass. Then it dawned on me that I could biamp the speakers using the Peachtree to drive the uppers and the NAD to drive the lowers. As these are pretty power hungry speakers I thought this might be a decent solution. Does anyone have any thoughts on this? Would it be beneficial to drive the LSi25s this way?
