Okay using the S&V test tone, I was able to calibrate my system at 85db and sounds great. I don't know if this is really the behaviour, but after calibrating at 85db using S&V test tone, I run my receiver internal test tone at same volume level (ref), the SPL record only around 78db. Anyway, I had enough with the calibration, almost every weekend this is what I am doing...so time for me to be contented on my current settings, relax and watch movies, listen to my CDs...hmmm I have 3 movies to watch this week, Scorpion King, Lord of the Rings and Panic Room.....ciao
