Well if you don’t want the new codecs stick with the HD621.

Personally I sold my Meridian surround setup and went Meridian 2 channel with a view to putting a Japanese surround processor in, however, after a few months of faffing about I realised I didn’t miss the surround at all and just connected the stereo pair to my front speakers admittedly they were DSP8000SE’s. However they have now been sold and for movies I use an LG ‘Atmos’ soundbar which is more than sufficient for my needs YMMV.
