If bluray/DVD via hdmi into a CBIII is inferior to, say, an Oppo SE into an SS, the update is a failure, particularly with either of the upper end DACs. If two channel music out of the SE via analog is better than coax into the SupII or Extreme, ditto.
Since the compli announcement. I've posted here about the hope of ARC w/the processor -- it's an obvious way to add value to both pieces and separate the system from the pack. Charles Hansen indicated it's not too difficult to do, but it doesn't appear Theta's done anything other than incorporate HDMI, no other value added. Maybe the power supply, but that might just be an HDMI card req. I think the superiority of the CBIII has always lied in the quality of the volume control, and it's digital 'voicing' -- remnants of the old Theta. We'll see what's up moving forward
