Why would you need to replace the 722 'soon'? If a processor that supports the new codes comes along from Meridian, surely the 722 would still be able to supply the required bitstream to the new processor. I don’t see why it shouldn't remain valid until it runs out of your desired HDMI upgrades. (And who needs 8K anyway?).

Edit: I agree with you on the timescale and the key decision (for those who give a s**t about the new codecs) is do you wait (probably several years) for M's contribution of jump ship via the 271 etc.

i guess the Marantz is that hydrogen fuel cell autonomous car available today at half the price of the junky tesla. (btw, would never ever equate M to the junky cash burn taxpayer subsidized scam that is tesla.)

To make a free selection of sources. Not every source can decode newer codecs such as DTS-HD MA to 8 channel PCM. Then the only option that remains is lossy audio.
In the long run, more channels might become attractive as well (Atmos, etc.). But that of course requires a decoding solution which might or might not come.

And that's the big question. Is it able to extract the audio bitstream of any of the new formats and pass it through to a future M processor? If it can do that, it's perfectly fine. If it can't, it will require yet another replacement.

Need, probably no one, but then again who really needs 4k or 2k? There was a time, when laserdiscs to 7" CRTs made everyone smile. Later it was laserdisc with a quadrupler to 9" CRT, then DVD, at some point digital projection and so on. So who wants 8k? Probably alot of people, I certainly do. Of course we need more content and display technology to get better.

I think it’s highly unlikely that decoding of Atmos, DTS:X etc. will ever happen in the player - think about much data would be required (speaker layout, positions, gains, bass managment etc.) for 12+ channels. The player would have to be the processor as well. HDMI chipsets have allowed HD bitstream passthrough for yonks (3D codecs included) and I’d be amazed if the 722 didn’t support it when\if required.

As for 8k, pixel count already exceeds what’s visible for display viewing and IMHO it’s only VR applications that will benefit from higher pixel counts. Image processing is far more important. See this thread if you need convincing.

To clarify, do you mean HDMI to HDMI passthrough (which I don't doubt at all) or HDMI into the 722, extracting the HD audio bitstream there and passing it through via MMHR to a future M processor (which I have my doubts about)?

Since the 722 has two HDMI outputs, another option would be to hook up one to TV/projector and the other into a future M processor, which would then require at least one HDMI input. Since Meridian always said they want to keep HDMI out of the processor, I consider this unlikely. Guess we have to wait and see what happens.

Yes, you’re right, nothing is certain regarding what will pass through the MMHR connection. (Although with the HD621, we do know that you can send two 2Ch bitstream via one SmartLink connection). Surely, M will make it happen if they do indeed bring out a more advanced processor and surely that can’t expect their customers to invest in further HDMI switching kit. However, at the present, the UHD722 is being sold as a 4K upgrade for their existing processors and should be purchased as such.

If you want Atmos etc. in a reasonable timeframe, IMHO the 271 is the way to go for a DSP speaker set-up. Looks like the new Trinnov 16 model has digital outputs (when they get enabled) so the price of an all-digital 271 solution is coming down (but still expensive).

I was told the Altitude 16 is analog only and will not have a digital option.

The Altitude 16 has two AES67 audio outputs (when they’re enabled that is)

Heard the same thing about the Altitude 16, analogue only. For a digital system it seems to be Altitude 32 and Datasat RS20i, both of which are limited to 16 channels when using the digital output. I think someone mentioned to me there's going to be a 32 channel digital upgrade coming for the Altitude 32 in 2018. Another option (have not heard it yet) seems to be the Storm Audio ISP, which already does up to 32 channels with digital output, but I think everything is downsampled to 48kHz. CBIV might also be an option but limited to 11.2 (?).

Again, not that I need the number of channels, but when investing a larger sum into equipment, it might be something to consider. They're all in a similar price range as the 861v8 and v8 is probably even more considering most of us went from v4 to v6 and then to v8. I've been out of the DIY audio electronics game for a couple of years, but I still wonder if a modern and cheaper processor like a Marantz or Arcam could be modified for a digital output. No idea what chips they're using these days and if it's even possible. But I guess that's really a discussion for another thread. Will do some digging and post if I find anything.

Well the Altitude 16 unit does have two RJ45 audio outputs on its back panel and I heard (second hand) that Trinnov planned to enable them some time this year. Could all be BS of course smile
