DUDE!!! That is an awesome setup!!! Yes I get the upgrade bug part of your post. I think that is half the fun of this hobby.
I love the McIntosh gear. Always have been a huge fan.
One other question... what are the dimensions of your room? Standing waves are one of those nasty things that are hard to tone down.
I have used Audyssey room correction before and have had VERY mixed results. In on room it worked fantastic and another it really muddied up the sound and I found using the basic distance settings for delays and speaker level settings worked better. I think the problem lies more with my room and the software trying to correct for poor room treatment on my part. If it has to overcompensate too much with EQ I find it hurts rather than helps. AGAIN... my personal experience ONLY!!
That being said - the Audyssey has some very good compression settings for just your situation.
Would you say that overall you find the DX hard to hear with films in general?
Is the dynamic range of quiet to loud a separate issue or the main problem?
I don't have your Control Preamp so I found the manual online. PG 37 discusses the Dynamic Volume (dynamic EQ) settings. The Dynamic Volume should help you with the overly loud issues - it has 3 levels of compression depending on your likes.
BTW - I do like the Dynamic EQ. It is basically a loudness contour (Fletcher Munson Curve) setting. When you turn down your level the bass suffers more than the 3k - 4k range and need to be adjusted upward a fair bit... I forget how much but roughly 10dB to sound equal in volume. What does this mean. When you are listening back to at a lower level it will adjust those frequencies to keep the overall tonal balance the same. It should still sound rich and full even at lower levels.
Page 30 of the manual discusses some other surround settings your preamp has. DRC is one of them which will work with the Dolby True HD tracks. It also has a D.Comp setting as well. I am not sure if you can run both D.COMP along with Audyssey Dynamic Volume and I would recommend double compression, but then again... Hmmm... maybe two light compressors would be better than one HEAVY compressor. That is something I would do in my own mixing/editing environment.
If you are running the Audyssey and like how it sounds in general, then lets just start with the settings on PG 37 and set the Dynamic Volume to at least medium. This will be a subjective setting as only you will know if you want more or less dynamic range.
So...
1. Room size
2. Is DX low overall?
3. Is DX fine, then things get too loud during action scenes. Too much Dynamic range?
4. When you ran the Audyssey calibration, how many sample points did you do?
Best,
Drew
