I agree with everyone else, it probably isnt your amplification.
but if you are looking for a retro look, 2 channel amp, that has done some duty driving M22's in the past, look no further than this vintage sansui. It has been frowning at me everytime I get out of the car. It feels left out since it has been exiled to the garage.

i dont remember if you have a sub. if not, maybe that will help
