Hi,

That last firmware version for the 568 is v1.55.

It still does a good job with vanilla DD/DTS, however, for lossless multichannel (from Bluray) you would need a 568.2mm (or 861v4/v6/v8) and a HD621 (or UHD722).

There are of course non-Meridian processors though performant some would say less musical .. horses for causes as they say.

Regards,
Carl
