For music I currently run a pair of M3's with a Technics SA-DX1040. I'm pleased with the sound but not overly ecstatic. I would like to use the receiver for movies but I would like to get separates strictly for music. I'm on a very limited budget and am interested in using the AMC 1100 preamp with their 2100 stereo amp. Im wondering what the effect, if any, there is in connecting the M3's to both amps with two pairs of wires for use at different times. I have a feeling that there will be no problems but I just want to make sure. Thanks
