I am trying to minimize the number of times the video is processed.

Please post your findings.
Do you have the capability of measuring the DD performance in Pure Direct, Direct, standard modes to see how they differ?

I am watching the Ella Enchanted with my kids now and I have to say, it is vey bright.
Noticeably brighter than my Onkyo PR-5507.

The input stage of the power amp inside the SubMersives seems to be rather sensitive. Corner placement (usually a very bad position for a sub) wouldn't help either of course. Mine are placed at the best spot available, luckily convenient as well.

As was mentioned earlier, weeks ago, in this topic: the Marantz, like most AV-amps, decides to mark the speaker as large if the -3dB point Audyssey produces is sufficiently low. Don't worry as you can adjust it later. If they had set it to small many other owners would complain about that. Theoretically all speakers could be used to aid in reproducing low frequencies, but in practice most speakers are far less capable than subs for this purpose.

I got my 8801 and started set up this evening.

I have some issues with Audyssey Set up.

Issue #1 - I use a Seaton Submersive HP as Sub (Currently only one, but getting another soon) and it initially said was loud and to level match. Even after turning it down to zero, was running hot. I asked to skip this test. I then manually set the level to -12DB and my Radioshack was still showing 84DB.

Issue #2 - I ran Audyssey again and this time skipped error with SW. It ran whole test (just did one position) and then asked to calculate. When I checked the results it made my left and right as Large and cross over for rest set at 60HZ. My L/R is Klipsch Ref RF-7II. I would like that to be set as Small and then set the cross over to 80HZ. Can I make these changes after the Audyssey is run?

I appreciate any help in this area.

Besides the 8801's DTS Neo X 9/11 processing bug when playing Dolby THD or DTS MA tracks, there is also another bug (Audyssey Pro configuration in my case):

- the Internet menu interface (of the 8801) only displays 1 single subwoofer (SW), even though the installation has 2 and when these 2 subs have their own individual distances and trims available through the internal menu.

Now the 4520 I am coming from, also had a bug displaying correctly a 2 subs configuration in the Internet interface, but the 8801 goes even further in this bugging... as it only "sees" 1 sub when there are actually 2...

So let's hope that this will be also addressed in the new FW...

No way, anyone could hear that.

However, there are effects that DSP's and processing have on the soundstage that I feel completely dwarf that issue.

I will run Audyssey during the week when the children are at school and I have a shot at creating a quiet environment.

The simblance you referred to also bugged me. In time, it goes away.

I think you'll find running Audyssey to get your levels and distance will make a huge difference. Even if the room isn't perfectly quiet, you can run Audyssey and then turn off Audyssey. At least that way you should have your distances and levels closer to being correct.

I do not have the equipment, but I am certain if it could be easily measured because anyone can here it.
This is an interesting case since this is supposed to be an analog path. So I cannot explain it.
I expect anyone with a good set of speakers should be able to hear this.

Also, The XLR inputs (like the PR-SC5507) are digitized (A to D) in some cases since they are processed.
I suspect they are not as direct a path as the 7.1 in's since they do not sound better and are also a bit brighter in all cases.

Fortunately the 7.1 in Pure Direct mode seems to be fine and fortunately that I also ordered an excellent source (Oppo BDP-105), otherwise I would cancel my order first thing tomorrow.

RichB, I re-read most of your posts, with Audyssey active is the treble boost apparent? If so, can it be easily compensated without further SQ loss? Do I need Audyssey Pro to adjust the curve? It appears that some physical (electronical) cause is behind it (which would mean further loss to compensate). Either deliberate or caused by bad design. Jitter from the video board or DSP board for instance, like was present in the flagship Anthem and to some extend in the flagship Denon (both discovered by Hi-Fi News magazine iirc). My guess in that case is the DSP board, since the 7.1 Pure Direct mode will probably switch off that one (not sure if the video board is active at that time).
