Hi all, i have a dilemma. I have an Onkyo txsr 600 and i have used the S&V test disc to calibrate the DD levels. But the Onkyo has it's own internal test tone generator. When i test the DD on the disc with my trusty spl meter, the levels are balance, but when i test with the internal test tones, they are off. Which should i use? I can't store different levels for DTS AND DD on the onkyo.
