I have the Axiom M80,VP150 and 4 M3's. I really like the package for both 2 channel listening and movies. The sound is fairly neutral. The sources are played back as is. For example using CD's they sound great. I tried an IPOD just so I could say I tried it using both the headphone jack and the USB outlet. It sounds awful. The speakers play back the source just as it recorded. Use a bad source, get a bad sound. The M80 have a high efficiency rating on paper, my experience is that they need a lot of power for higher levels. I thought this was just my experience, but my friend also has them and he tried using a Denon 3805 (two channel only) and he found the same thing. At higher levels you need very stable power. We both wound up using another amp. I use an ATI 1202 while he using an Emotiva (125x6). If you are using the 7500 it should be fine. As far as the Aperions, I have not seen a bad review and was tempted by those but went with the Axioms. I don't think that you'd go wrong with either choice. Both have good reviews and the dollar value for both is very good. They both eliminate the middle man so you get what you pay for.
