I have mixed and matched various components through the years. I have also prided myself on finding good sound with inexpensive components. My latest system consists of an Onkyo A-9555 Class D integrated amp, an Onkyo DX-C390 CD changer, Axiom M3v2's, a Dayton Audio (Parts Express) 10" sub and a pair of Signal Cable Analog II interconnects.
To say that I am pleased with the sound is an understatement. The M3v2's still continue to amaze. Combined with the Dayton Audio sub (at $99.00!) I have full range sound on the cheap. And the Onkyo integrated is an amazing piece of equipment. The Onkyo amp is the most expensive piece of equipment in the system, yet still came in at a a hair under $500.
In my listening space, these particular components sound amazing. I am more than pleased with the "lowly" Axiom M3v2's.
Here are a few pics of my setup:
