I hope this does not qualify as hi-jacking it is on topic. I am in the same position and am getting ready to calibrate my system. I have DVE and not Avia but I hear that they both do the same thing. I have read the above posts and get 99% of it but my question is; when I watch movies right now I turn my Yamaha RX-v630 in between -40 to -35 and it is loud. If I calibrate at 0 is would be deafening, are you really supposed to calibrate at 0?

Thanks Mike
