Well I just chanced across this thread and indeed am thinking about moving to 4K but the impression I get is that it's still in a sh*tty box that doesn't exude M's style nor match their other kit (not even as an option) and should have more inputs and especially outputs for 2000GBP.

What you really get is a bog standard if decent off the shelf video board with I assume a token bit of M hardware too and a price that smacks of should be 1000-1500GBP even at M prices but lets charge 2000GBP and give a discount to get some quick sales to shift the batch of video boards we had to buy, existing users will think they are getting a bargain, M get some revenue and in a year or so we can chop the price back to the HD621. Not saying it's wrong by M to do this but that what it looks like.

Oppo audio into HD621 and 2nd HDMI separate video seems to be the rational path here, it's the only source other than streaming that I'm really looking for SQ anyway.

With both Richard and Bob out of M; I continue wish M every success but sorry my loyalty left with them.
