Amplifier Dilemma

If your virtual system listed is the one you currently use, I would probably suggest a different amplifier and perhaps experiment with speaker placement. That can make a huge difference with maggies, especially distance from the back wall. One integrated I can tell you to stay away from (my opinion only, of course) is the Pathos classic one. It doesn't have enough power to drive your maggies unless you listen at very soft volumes. Second, I don't think it sounds that great. Again, just my opinion. Of the ones you listed above, I would be most tempted to try the Classe. However, if I were going to buy the 101, I would probably wait and save up for the 151. You can never have too much power. Hope this helps.

My current speaker wires are cheap Acoustic Research. My next move will be some good speaker wires, then a better amplifier.

Before changing any equipment, I'd advise experimenting with cabling in order to find out what your existing setup can really do. Cables can make or break the rig.
Upgrade AC cords, interconnects, speaker cables, & the way that they synergise with your componentry are, I suspect, the remedy for your disatisfaction.

I just switch from a HK 2.1 amp to a Anthem Intergrated 2. And that is the best 500 money can buy! You night want to try a hybrid intergrated amo like INT2, which has a tube preamp and SS amp all in one.

The Magnepans need a lot of current and the Odyssey would simply amaze you. It has current to spare. You can try it at home with no risk. To get the best bass, put it on top of some black diamond racing cones and a slab of granite.

My selection is down to these bad boys:
Aragon 4004
Classe CA 101
Odyssey Stratos

The question now is, which of them have the best treble and mid range.

Should I add Bryston 3B to the list?

Keep those responses comming, I need all the help I can get.
