All right, let's turn back to topic please.
I have seen announcements for the RMC-1 as a 7.3.6 capable processor, but the backside clearly indicates that 9.3.4 is the standard / preferred operation instead. It is my opinion that 7 speakers is sub-optimal for horizontal panning and recently I came to the conclusion that 6 speakers is over the top as far as "top" speakers are concerned... Will the RMC-1 even be capable of running 6 top speakers?
I designed and prepared for 6 overheads (TF/TM/TR following Atmos Guideline position), but they are so close to one another that I reckon 4 are enough. And with those 3 gigantic LCR, my front stage doesn't need Front Heights.
Just have to decide whether to keep TF at 35° elevation or move the pair 50 cm (20") closer to MLP and have them at 45°. Suggestions?

Here for you guys: [/DreamingModeOn] It would be really great for smaller setup without any height channels that the unused channels could be (partly) re-assigned and used to make active cross-overs for used channels. For example: Sub Left => Bass Left front speaker L Front => Mid Left front speaker LF Height => Treble Left front speaker same for Right channel. And possibly also for surround and center channel a similar, probably 2 way assignment. Well the hardware is available just "only" software is needed. [/DreamingModeOff]

I never really considered 6 ceiling speakers because I knew that would make my ceiling awfully packed. I have 4 planned.
From all the reading that I did, I concluded that ~45 degrees was a good place to be. May not be the best answer though. EDIT: I forget where I ended up pricesely in my placement. It might have been closer to 40. I had lots of ceiling obstacles -- because I'm using backer boxes.
I got frustrated when reading about ceiling placement. DTS-X vs Atmos placement guidelines... and some comments that I read suggesting that round or coaxial ceiling speakers aren't the best.
Feels like there is an awful lot of ambiguity.
The only way I could see the RMC-1 driving 6 ceiling speakers would be if the outputs were assignable.

Interesting. With each channel getting its own (stereo capable) AKM DAC running in mono, it sounds like what Teac did for a stereo DAC: www.absolutesound.com.sg/news-updates/why-did-teac-use-the-ak4490-dac-in-the-ud-503/"Kato: Yes. As you kindly mentioned, both the UD-503 and NT-503 have been designed based on TEAC’s traditional “dual monaural philosophy”. Of course, the DAC design is fully capable of clearly separating L and R channels, but our standards do not tolerate the slightest interference, so dual AK4490 are employed for L and R channels, two in total." I wasn't familiar with using a stereo DAC in a mono config... Both my Eastern Electric MiniMax DAC Supreme and my Astell & Kern AK240, both of which I purchased new in 2014, have two DAC chips in them (one for each channel). Running the ES9018 chip in mono mode yields 135 dB DNR (Dynamic Range) vs. 133 dB DNR in stereo mode, but the new ES9038PRO offers up to 140 dB DNR (yuppers... that is a whopping 7 dB higher than anything made by AKM today).

I would have thought so too. My understanding is that Dennis Erskine has argued against round wide dispersion speakers in the ceiling sounding bad. (Ok maybe "less good"). I recall it from some AVS thread.
Why? I'm not sure I understand why. Perhaps the dispersion is too wide and should be more focused on the listeners? I've heard of angling ceiling speakers towards the listeners.
I've seen him use very small Triad speakers angled toward the listeners in the ceiling. They weren't round wide dispersion speakers, I recall that that much.

he also leans HEAVILY towards triad...do they make a round coax? if not that would explain his views

Here for you guys: Looks great! Peaked my interest. Maybe some of this has already been answered or it's too early, but I have a couple of questions... - As others have mentioned, can the AM / FM tuner become an expansion module and therefore use that space for something else? I wonder what the breakdown between those that listen to AM / FM is vs those that stream audio. Personally, I can't recall the last time I listened to AM / FM in the car, never mind at home.
- The ethernet and a USB port is in the same section, so why an additional separate USB port? USB 3 supported? Why USB B port? Can you connect a USB drive for audio / video streaming?
- Will this be a networked device? In other words, can it stream audio / video from a NAS device or network share? Or is the ethernet port simply for Dirac configuration and firmware updates?

another processor was introduced at CES (I cant for the life think of the name) which is only 5.2.4 with dirac....and its retail will be 5500$
the RMC-1 is looking better and better

No coaxial to be found on the triad website! I think wide concentric dispersion is needed for the elevated spakers as these are usual rather close to the listeners. For me it's coax for TF+TR but SEOS horns with superior horizontal dispersion for ALL ear level speakers. BTW I made a test speaker based on the Volt V10 but with another tweeter and it sounds utterly fantastic. At the same time, surfaces need to be treated or that wide dispersion is causing unwanted levels of reflections.

Not so much the 5.2.4 format --- but that it has Dirac and is in the $5k ballpark. Does Datasat have a new "budget" (cough cough) processor maybe? Just thinking through who has Dirac... not many.

You will be able to get an XMC-1 at 5.2.4 with Dirac for much much less than $5,500.
