Avia Vs. Reciever Test Tones

[ClaytonMG]

Right now I am trying to figure out what's more accurate, the test tones on Avia or the ones on my reciever. All I am trying to figure out is the speaker levels. I know that when I test the Avia disc, I have THX enabled so that might change things, but really the avia disc is about 4-5db quieter for my rear speakers than the test tones are on my reciever. So, I ask you guys, which ones do I go by?

I would probably have someone come in and do a complete analysis of the audio characteristics of your room (peaks/nulls) if you're that concerned... or can't decide what ways sounds the best to you.....

or you could split the difference

Quoting from the SVS site:

As the tones start, alternating, speaker to speaker (watching your sound meter now) set each speaker’s volume to 75 dB or 85dB (depending on your tone source), using the receiver’s channel controls. Not all test disks or receivers are the same when it comes to calibration tones however, if using a test DVD like Video Essentials should allow you to calibrate reference level at 75dB. Ovation's "Avia" DVD is recorded at a higher level to improve signal to noise ratios during calibration, so you need to measure instead to 85dB for all channels if you use it and not Video Essentials (discussion below, regarding a "boost" to your LFE still applies but you simply add the bump you want above and beyond 85dB, vice 75dB).
