HDMI 2.1 chips in AVRs and AV processors - transition to 40/48 Gbps, issues with video and graphics features

JVC has arrived with HDMI 2.1 projector hosting two 48 Gbps ports, for all hard-core enthusiasts of high bandwidth signals.

Apart from LG TV 9 series, this is another device showing some limitation of new AVRs with 40 Gbps ports. Luckily, the projector has two full speed ports, so one can always avoid AVRs.

Yamaha has just released a demo video with beta software in gaming action on 2021 AVRs. No big excitement promised. There is a guy playing games. He turns his back to the camera. It's weird! Impossible to see diagnostic screens and data specs passing through AVR.

Probably beyond most people's budget, but here yah go:


This 8K support will be applied to three of the ten HDMI ports such that one of the inputs and two of the outputs will have this 8K/60 and 4K/120 support as well as offering many other advanced features including: Quick Media Switching (QMS); Auto Low Latency Mode (ALLM); Quick Frame Transport (QFT) and Variable Refresh Rate (VRR). All ten ports will continue to support 4K/60Hz.

Replacing the 4K version, which is now no longer available from McIntosh, the new 8K version of the MX123 A/V processor is priced at £10,495.

Also, another one for those with deep pockets:


The two new AV devices will have HDMI 2.1 factory installed

These two new models take the functionality of the current SDP-55 and SDR-35 respectively and add a HDMI 2.1 video board as a factory-installed component.

Note that there is also an HDMI version 2.1 upgrade option being made available
for the SDP-55 and SDR-35 models.

Sound United is releasing multi-input HDMi 2.1 adapter, as hinted by Roland Kruger several months ago in a video presentation to German audience. Those adapters will not be available for free.

It seems there will be a revival of interest in Onkyo, Integra and Pioneer new line, especially now with those secondary solutions such as additional external adapter boxes. €200 for a multi-input adapter box sounds laughable, but it is what it is.

First Onkyo units have arrived to owners and initial reports suggest that three 40 Gbps ports are working fine at the moment. Plus, they offer Dirac system, which is great, and Dolby Vision 4K/120 pass through seems to be working too. Let's see more in-depth testing results once those are reported.

Think Onkyo, Integra and Pioneer AVRs will be very competitive as those are priced reasonably and do not require use of any additional adapter boxes.

I don't think Onkyo and or Pioneer have any current plans to start selling in the UK again? Onkyo appear happy to leave things as they are?

Yes, true for time-being. UK a bit later, Q1 2022 hopefully, once distributor is found. This is a hint from email exchange with their management, which I am not able to find at this moment. They certainly have an intention to come back, which would be great for all consumers.

Sony's DN-1080 has been discontinued, so hopefully that means a new 2.1 compatible Receiver is on the way.

Or that Sony are no longer intending to make AV receivers?

They may even be withholding any new AVRs they make from the UK and only making them available elsewhere in the world?

New Denon S760H was spotted in Costco - with three 8K input ports. We think all three ports are 40 Gbps, managed by a new HDMI 2.1 chip as present in new multi-input adapter. A few people have already bought it.

There are no official announcements as yet or online manuals.

Ports on this budget AVR are 40 Gbps, indeed.

need to upgrade amp, decided to get sr5015

after doing some research that marantz receiver with sn from 70001 upwards are hdmi 2.1 bug free, i start to ask some online store here in my country whether they have sr5015 with sn 70001 upwards or not.

sadly, they all dont have it. all sr5015 are with sn below 70001. and they dont mention the adapter either.

but, finally i found one store that says they have sr5015 with sn below 70001 but with adapter spk618 supplied, with reasonable price? at around $899 brand new.

so, for you that live at the country outside marantz list at their website that offer free hdmi adapter, try ask your dealer about the adapter. Who knows they might already have it..

here it is, didn't have the time to setup it yet.. maybe this weekend..

few days later.. it turns out that the other store are to lazy to ask the marantz dealer/distributor about the free adapter..

btw, anybody knows what dac chip used in sr5015?

If you have it with the adapter, then it's an older chip from 2020.

You might have noticed in my post #117 above that Sound United is about to release models with new chips and three HDMI 2.1 ports. New model from Costco is a curious case.
yes i'm aware of that, some say the newer uses lower quality dac.. the older uses akm dac chip (i read it somewhere.. for denon x4700 and marantz sr8015 if i'm not mistaken..)

i'm just curious what dac chip on older sr5015..

I think the denon x4700 and marantz sr8015 are now eye wateringly expensive £1550 & £2779 once I would recommended without question, but with the NAD t778 at £2499 with a stably running Dirac for some years now, not so sure.

So when are we likely to see it at a costco over here as it's looking like the prime candidate to replace my aging Yamaha RX-667 :)

No idea. There are a few owners who bought it in Michigan and elsewhere.
Anyone we can reach out to?

Really does seem like they are maintaining marketing silence in order to not highlight that all 2700/3700/4700 etc owners have less hdmi 2.1 capability than the entry level model and would be required to pay three figures to get the 3in1out switcher to rub it in some more :(

@Andy Bassett hello after your recent article about the HDMIs on Denons, would you be able to reach out to your contact there about this please?

Seems very bizarre, a new model 760, yet no mention of it on the Denon USA website?

To us consumers at AVF, visibility of what may be coming could be useful. :)
