I posted this elsewhere but I'll try here also. Hopefully I can convey what I need info on here. I have an Onkyo 898 that emits test tones to all 7 speakers for calibrations. When I calibrate my system correctly this way and check it on a 5.1 surround track that plays all 4 rear/sides together the calibration is way too high. Example, I calibrated using the internal test tones to 75db for all 7 speakers perfectly. Then I put in Avia to calibrate at 85bd and check everything. It checks out perfectly until I get to the rear/sides. When calibrating the rear channels it plays both the sides and rears simultaneously and I get about 89db on the meter. Should I go with the Avia or the Onkyo?
