Hey again,I have heard of people saying that even when telling ARC to limit corrections to a certain frequency that sometimes it still corrects above that frequency. Maybe that is what is happening?
Also, ARC can be very subtle in some situations where it decides that doing more to the audio would create some harm, so it might be doing very little in your room, I suppose.
That said the fact that the unit sound dull versus your older processor is a little strange. Does it sound this way when ARC is off?
I can't hear what you are hearing of course, but if this was my setup, in the absence of any better advice, I might do a factory re-set and run ARC fresh with ten measurements all within a foot of where my head is when watching a movie....
I want to say ARC off may have made it a tad brighter/more neutral but ARC OFF was much louder so I didn't try it long. I'm assuming I would need to take an SPL meter and use test tones to get all of the speakers level matched to 75db (maybe not?)
I have heard others mention the highs especially being dull compared to other receivers so it may just be the sound signature the Anthem has. Everything else sounds great so it is kind of bothering me.
Also, I do believe ARC must still be doing stuff past the frequency cutoff which is why I am getting an even duller sound on the highs. I can test ARC OFF but it is much louder so I have to turn the volume down quite a bit which is going to affect my sub volume as well. If I lower the volume with ARC OFF I will probably need to increase the subs by a bit, especially because I use room gain.
