I might be able to test using the amps in the 4311 (if my speaker cables will reach)....but I don't hear the harshness when I use the sound equalizer thru the same amp, so I'm not quite sure what that will prove. Doesn't mean i won't do it....it's just unlikely to be the problem (NHT Power 5).
Let me step thru this calmly on Monday. Something is wrong..probably me
but I'm pretty experienced isolating problems.
One thing I am going to do is get the sound equalizer out of the path. We now know that both the sound equalizer and 4311 see the same before curves in the pro software (I have them saved) and that was important to see.
I have not run the 4311 with the pro equalization because of the sub curve which likely means I did something wrong so listening would probably have no value.
If my other measurements are correct (forgetting for a moment about the sub), then it's really looking like something is happening as Denon applies the Audyssey corrections.
I'll go thru it methodically on Monday.....and send whatever I can capture.
One other thought is that the NHT 2.9's are known for their directionality. I may be setting the microphone too wide from the sweet spot, because I sit almost directly in front of the left front....so I use that as postion 2. I'll try setting the 4311 taking all readings within the sweet spot and see if that changes things. However, I am using the exact same measurement points for all my testing so far...and I don't hear the harshness when use the sound equalizer...only when I use the 4311's XT32 so this is an unlikely path.
Have a happy new year's eve and don't drive tonight....
I haven't really tried audyssey dynamic eq at all yet.
