I'm wondering what benefit I could extract from buying Avia and an SPL and doing calibration on my system in its current state. I've got: Paradigm Studio 60's (L&R) Denon 3802 (picking up from UPS tommorow!) Sony KV27FS12 WEGA I've gone into service mode on the Wega and turned off red push, corrected the over squeeze on the 16:9 enhancement mode, and set the 'Movie' mode color settings to the same as someone else who calibrated the same set using Avia and posted the results online. I'm not familiar with audio calibration in general, but I'm wondering what benefit I would obtain with only two speakers connected? Similarly, I don't know if there's anything else I could correct with my picture through calibration. Any insight would be appreciated.
