I'm interested in adding a Parasound A31 to an existing Pioneer Elite SC-61 using the pre outs. The speakers I'm using are Paradigm Monitor 11's and running 5.2. I'm only interested in using the Parasound 3 channel amp for the front stage only. My question is, should I run Pioneer's MCACC calibration after I do this? I haven't moved any of my speakers and was always told only to run calibration is you have moved your speakers. Any thoughts would be awesome.
