I turned it off and rebuilt a kinder, gentler version. ;)\nMy little room is pretty lively, and I know that my speakers aren't to blame. I experimented previously with my GEQ making a little swale of -1.5dB at 2kHz, and -.5 at the neighboring toggles. With this instance, I did -1.38dB in the Curve Editor at 2kHz, and had to play with the points to get it a little smoother coming out of the dip, but it works! There's a cut from Tori Amos, Northern Lad, that exemplifies this: in the chorus, her voice just hammers me. I listened to this one day for an hour... the Lady was about to go all Snapped on me!... but between Audyssey On with the Mid-Range Correction On, Aud. Off with nothing, and Aud. Off with GEQ enabled, I could listen with that minor dip I made.\nI tested it again today after building that in to the curve editor. It's a -3dB crater the way Audyssey is programmed. By making it shallower and a bit wider, I don't notice a dulling in the frequencies the way I did with MRC ON. Overall, the tunes are still lively, but that 'perking' of my ears isn't a thing now.\nSince I learned I do have a sensitivity to something that matches with listening fatigue, this alleviates it. In this room. If I set up in my greatroom, I might not need it. Or, when I get a little extra damping action in my room (Curtains for the windows, a little bit of diffraction, etc),we'll see how it tests out.\n;)\n\nThank you for confirming my suspicious, as I did notice your mrc being a little shallower than the default one. I don't use my HT set up for music so to me I wouldn't bother customizing anything other than the bass but good to know it works well for you. Great idea! This also confirms the original BBC (iirc)'s idea of mrd (d=dip) has merits afterall, at least in your enviroment\/setup!!
