Which should I trust? My Denon test tones, or THX Optimode test tones?

    The reason I'm asking, obviously enough, is because I get different readings depending on which I use. I don't mean one is louder than the other, though it is, I mean the levels appear skewed with my Denon, but balanced with the THX Optimode tones. Which to believe?

    I've started experimenting with a sixth rear speaker, and the Optimode doesn't put out a test tone for it, so I might have to use the Denon...but if the Denon's test tones are off...

    What do you think?

    I would stick to the Denon's test tones. The THX tones can vary from disc to disc depending on what db level it was recorded at.

    Or better still... Pick up a copy of AVIA or Video Essentials and use the test tones provided. I tend to believe they are more accurate than a receiver's internal tones since they are sent from the source unit (DVD player) and not generated by the receiver itself.

    I would go with software tests. When you play a disk through your DVD player, through your cables, and into your receiver, and processed and decoded, the sinal could change very much. I was always told use a disc to calibrate. Using just the receiver tones could make for an incorrect calibration.
