I disagree. HDMI 2.1 and eARC open up the possibility of decoding the new codecs externally and sending the uncompressed LPCM stream over HDMI into a UHD722 for audio extraction into MMHR. Meridian have always stated that the 861 architecture was capable of supporting more LPCM channels when required. My 861v2 many years ago even had little stickers to label the channels!

An HDMI 2.1 UHDxxx capable of receiving 16 uncompressed LPCM channels over HDMI and outputting them over 2x MMHR connections to an upgraded 861 or future G series product. Well now, that would be worth the £1,500 upgrade cost. I might even pay the full £2,000 for it. It even fits into the current Meridian ethos of decoding elsewhere and keeping Video out of the processors.

As for any upgrades to the HDMI 2.0 of the UHD722 to make it HDMI 2.1 compatible I suspect that any features that could be added would be subject to a trade-off between features and bandwidth. In any case even if any firmware upgrades were possible the real question is if they are within the gift of Meridian to provide or would they depend on a 3rd party given that the solution was largely bought in.

Many thanks,

Anthony.
