I recently upgraded from Marantz 7702 and their MM7025. At first I replaced the power amp to your same Parasound A21. For a couple months I ran the A21 with the Marantz 7702 pre/pro. It sounded good but I wanted to upgrade another step and bought a Parasound JC-2BP. The change in sound (for me) was very pronounced.
The combo sounds excellent! I read a great deal of reviews about the JC 2, and in their words it has a "vanishingly low noise floor". I am certainly no high end audio reviewer, but this sounded exactly as I would describe it. IMHO, if you are looking to upgrade, save up and get something that will make a big difference and sounds great to you.
