So, I plan on doing the sb crawl tomorrow and ordered a tripod to get better result from my Audyssey XT configuration... Since my Denon 3311ci doesn't have independent controlled pre-outs for dual subs (thinking about adding second FV15HP) and the network board is bad (always says "Connecting" when trying to use any network related settings) I am considering upgrading my receiver.
Here are my thoughts for upgrading:
(1) considering future 4k tv upgrade in 1-2 years if I would need multiple HDCP HDMI 2.x inputs
(2) considering Dolby Atmos or Aura 3D compatibility
(3) airplay compatibility
(4) only need one extra zone for two living room speakers (already on zone 2 of 3311ci)
(5) all source compatibility with latest Logitech Ulitmate Home/Hub which I am using and works fine for me
I don't want to end up with a receiver that is not able to connect all sources to it's HDMI inputs in the next 5 years if possible, so I want the most compatibility in the hdmi interface... Would pay up to $3k for this receiver. Other option would be to get enough channels for my 8 speakers (not including subs) for possibly using Dolby Atmos or 3D Aura in main room and two channels for my living room and maybe this can be done with separate amp(s) and just upgrade the surround processor/preamp as hdmi standards change.
If I go the receiver route and it is too early to select a receiver based on new 4k hdmi standards not being solidified, I could opt to get something less expensive and buy me more time until I upgrade my Pioneer PRO-730HD projection to 4k in the next couple of years.
If I get a less expensive temporary receiver to meet all these needs I have seen the Denon x4000 and x4100w that seems equivalent to my 3311ci except that is has the better Audyssey xt32, dual independent sub control, and a working network board which will allow me to use Airplay but will be changed again once I get 4k assuming something like HDCP 2.2 is required for each source...
As far as possibility of using Atmos/Aura 3D, I only have limited speaker configuration and not sure if it will be adequate or not... I am in a large family room/Kitchen so putting side/rear floor speakers not as much an option as I would have in a dedicated theater room but I have 5 nice Speakercraft 8 inch ceiling speakers with 4 in a square pattern and one in center back of the 4. So I have 3 M&K s150 bookshelf for mains, currently 1 Rythmik FV15HP and 5 in-ceiling speakers.
