Don't Use the Audio Processor to Process Video
I think the Tide is indeed a Holy Grail because (alongside the AVR-16) it's the only AV processor ever to get close to stereo equipment performance.
MiniDSP thought long and hard about including HDMI 2.1 / HDCP 2.3 capability, and make a conscious decision not to do it. They explained their reasons.
Nobody is under any obligation to agree with those reasons. We have choices, and you just have to decide what you want.
If you think HDMI 2.1 is essential for a top tier AVP, that's fine, don't buy a Tide16. Get something else instead. Please.
But the continual complaints about the lack of 2.1 are like going onto a Porsche forum and complaining that the back seats of the 911 are too small.
I'm not a gamer and have no interest in this, but can I offer a different perspective about why the absence of HDMI 2.1 is actually a good thing?
Before HDMI, many manufacturers produced AVP's, but that number, and the ensuing competition, have dwindled due to the technical difficulty of implementing HDMI, and keeping up with the never-ending specification evolution. It's a problem for AVPs because audio and video are unfortunately forced to sit alongside each-other in the same box.
Several people already mentioned using an HD Fury VROOM or similar to handle the video, leaving the audio to the processor. I think that works even better with eARC because then you don't send any video to the processor any more.
Other things being equal, having to use an extra box is undesirable, but I think it has two advantages:
(1) The AVP no longer has to keep up with advancing HDMI video standards - especially those associated with advances in gaming. The AVP is expensive, and you don't want to have to keep changing it. The HDMI switch is hardly disposable, but it's much cheaper to keep that up to date with technology.
(2) There are performance benefits to keeping digital video entirely out of the audio processor. For example, Amir measured the same performance using eARC as with USB or streaming on
the Fosi ZD3 and
Bluesound Node Icon - better than had ever been achieved with any AVP.
Therefore if you get a 48 Gbps HDMI switch to handle all the video, the audio processor can be optimised just for audio, and you can keep it for longer.
You chose the processor based on audio functionality / performance / price, so you can get better value than when you're constrained to getting an HDMI 2.1 processor.
Yes, the
HD Fury VRROOM (or
even 8k Arcana) is fairly expensive, but it's a master of all trades, and there are many good, cheaper, options:
(1) The
EZ-SW41H21A-EO is an HDMI 2.1 HDCP 2.3 switch. It accepts 4 x 4k/120Hz VRR / ALLM/ DV inputs, plus eARC from a TV, and sends either HDMI or eARC to an AVP.
(2) The
Orei BK-4927 is an HDMI 2.1 HDCP 2.3 switch. It accepts 4 x 4k/120Hz inputs, plus eARC from a TV, and sends audio HDMI to an AVP
(3) The
Orei BK-4929 is an HDMI 2.1 HDCP 2.3 switch. It accepts 4 x 4k/120Hz VRR / ALLM/ DV inputs, plus eARC from a TV, and sends eARC to an AVP
