You're still missing the point. The Volume scaling issue I mentioned exists on virtually all products using Audyssey, THX, PLIIx, etc. It drops the max available volume level when all processes are engaged. The Integra simply doesn't show the limitation it just limits max volume while still allowing you to increase it. In most circumstances this wont be noticed unless you are listening to sources recorded at very low levels like I mentioned in my review. It also depends on the efficiency of your speakers, the size of the room and the levels you prefer to listen at. Regarding your calibration issue: If I understand your problem correctly, when you hit the "test tone" button the SPL you measure is 80dB instead of 75dB for each speaker. If that is the case its likely b/c the high sensitivity of your speakers. The simple solution after you balance out all of your channels is to lower the master volume until you read 75dB for all of your speakers then note the master volume level so you can set it to that when playing back movies. Thank you for the reply. Perhaps I am "missing the point" but the fact remains that I can increase the MV of my system and see the resultant increase in SPL on the meter well beyond reference levels. If Audyssey is limiting the max volume it is of no consequence to me. Regarding calibration, the Speaker Setup Test Tones emitted by my processor are not governed by the MV of the processor :confused:. I'm sure is the case with the Denon and most if not all other AVR's/SSP's. If you are using an external source for test tones then MV might apply. My manual says the Integra Test Tones are output at 75 db. After Audyssey calibration, my main channels are running at 80db with the channel levels @ approx -9db for the LCR's. I agree with your assumption that this is due to the high sensitivity of my speaker as I previously stated. Since speaker sensitivity levels are highly variable, perhaps the manufacturers should allow the user to input the manufacturers’ sensitivity numbers into the speaker setup and then calibrate the test tones accordingly. Of course, that would depend on consistent (and honest) numbers from the manufacturers.:)
