Rodney, when I'm listening on a setup that has surround speakers available it makes sense to use them fully and I always use DPLII(or occasionally Neo:6 or Neural Surround)with stereo sources. The two front channels have surround ambience mixed into them(there was nowhere else to put it)in varying amounts which originally came more from the sides and back rather than the front. The DPLII or similar processing extracts this from the front channels and directs it to the surrounds where it belongs. The result is a little closer to the reality of the original performance.
My M22s do a superb job with my classical CDs and I'm sure that yours will as well. No need to deprive yourself of the great world of classical music that's waiting for you out there because you don't have "flagship" speakers(which title I've claimed for the M22s anyway). Enjoy.
