Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems Meridian UHD722 Trade-up promotion announced

Looks interesting .. There seemed to be an HDMI in but no reference to it in the review. I'm guessing multiple 4K sources would have to include an extra 4K switch as well.

I guess so, I just use mine for playing BD and as a Roon endpoint

It could possibly be just by updating the HDMI chipset from 1.4 to 2.0 level if jitter wins have been made in the HDMI chipset designs over the years. If we are able to detect it that is a different story.

It would have been nice if they would have a linear PSU in it though since that usually keeps noise even lower and is more listenable to the ear. Since this thing actually costs 2000£ and goes into high-end setups.

If you mean 4k game, the latency will be too long, what else?
For Netflix 4k, I think you could directly connect to your HD621.

You can either buy a source with two HDMI outputs, where one output is used for audio to the HD621 or...
buy a HDFURY (Integral or Vertex) to remove all the handshaking/copy protection nonesense. That way your source will work with the HD621 and not tell you that a non-compatible device is connected.

One output goes to the TV/projector, the other into the HD621. The video connection from the HD621 to the TV/projector is not required anymore. If you need more inputs, then add an additional HDMI switch before the HDFURY. If you have a single programmable remote, this is really no different than using the regular M remote, even though you're hiding one/two additional devices in the rack.

Hi All,

Reading the comments a few seem to have missed the pertinent role of the HD621 and UDP722.

These aren't HDMI switches.
(Well they are, I know, but I shall explain)

They are designed as Meridian's way to get the best sound from Blu-ray.
Think of them as a box containing the 'special sauce' that Meridian would have added into a Meridian Blu-ray if they had made one.

They take the multi-channel PCM soundtrack from DTS Master and Dolby True-HD off the HDMI signal, upsample and apodise it to 96/24, and pass it on to the surround controller.
This job is done in the HD621/UHD722 as it keeps the jittery HDMI signal away from the other signals in the controller, and as soon as possible in the chain to maximise performance.

It's more by way of convenience that they have multiple HDMI inputs, but that's not their raison d'etre.

Can I just clarify that if you have two 4k display devices - I have an LG OLED TV and Optoma UHD Projector in the same room - the UHD722 will not supply 4k to both?

Thanks,

Richard

Hi Richard,

The HDMI 1.4 socket on the UHD722 does allow 4k, but not HDR which I expect both your display devices will handle,
nor HDCP2.2 which they may well both expect.

So you'll need to use the HDMI 2.0 output of the UHD722 and then split it to your two displays.

This Wyrestorm HDMI Splitter, which we sell, would do the job.

Cheers,
Rick

Hi Rick

Thanks for explaining, I assume the board used in the UHD722 is bought in and so Meridian are stuck with 1x HDMI 1.4 and 1x HDMI 2.0 outputs, not what you would ideally choose to have.

I understand the frustrations of those questioning whether it's the end of the road for the 861 or not. I'd like to know too!

If v8 is the last upgrade for the 861, I'm still happy to buy the UHD722 so I can install a 4K projector and get another 4-5 years out of the 861. I don't know of anything else that would give me better sound for 2-channel (love Trifield) and surround sound than the 861v8.


Rather than invest in equipment for movie audio formats that may or may not make it in the long run, I'll stick with what's proven to me for now. I don't need to chase every new format with large investments into gear. M has a smart approach in working on making the proven / standard audio formats sound better than anyone and ignoring the noise. I'm a music lover first, so the sound with movies is just the icing on the cake for me.

I have a HD621 to trade in. What is the UHD722 cost and HD621 trade-in value in the states?

Is a group buy being setup?

Hi Russ,

Yes the HDMI video is bought as a complete board, and was of the highest specification available off the shelf.
Meridian could have fitted a bespoke one to a higher specification but that would have made the UHD722 much more expensive.

For me I don't really care the modern codec things, but hope M can add modern RC to the 861, actually I feel the MRC was a very good start, why not carry on?

I visited a local friend with new installed Arcam 860, sound wise I think it can not even beat the 568.2, but the DIRAC (impulse correction) really impressed me, we watched the David Fuster with his friend, heard the bass I never heard on my system.

Sorry for the off topic
