It's been a long time since I've been able to be involved in these forums (have a 16month old, keeps us very busy). Anyway, I wanted to also add something here on the 'popping' issue.
I've been emailing Bob Moran back and forth over 10 times on this issue as they are trying to resolve it (so they ARE working on it). V113 did not fix the issue totally, but did fix Audyssey. Below is a copy of my original email to Bob with my exact issue (may be the same as all you with the same 'popping' problem). It's very specific to HDMI input on my T-785.
Again, their engineers are working on this problem, so all hang in there. All new receivers with Audyssey (or other 'auto cal' system), and especially HDMI are having one issue or another and are comming up with firmware updates (NAD is not the only one). HDMI's HDCP is really a bugger for a lot of manufactures.
Thanks for this thread, is has a lot of information!!!!
I've finally spent some time with my T-785 (incredible receiver by the way!). There are some issues that I think are software related that you may have also heard from other customers. I have updated the software to V113. Before V113, there were problems with Audyssey figuring out 'type of speaker' and 'out of phase'. Also, there was a strong "POP" from the speakers, especially from the sub when changing to any source or shutting down the receiver.
After applying V113, most of the problems have been resolved. There is one specific "POP" from the speakers that occur only under a specific condition. This is:
When DVD is playing (and kept in a playing mode).
Audyssey is on in the DSP (on any curve - Audyssey, NAD, or Flat)
Source is changed to another source and then back to the DVD.
When this occurs, there is a "POP" from the speakers. If the DVD is put in 'stop' mode, this does not occur. Not sure if this is an issue with Audyssey, or HDCP (HDMI) or the combination of both. I know that HDMI has been a nightmare for software engineers due to HDCP and this may be one of the issues. The NAD is connected to the TV through HDMI and any other source playing that is up-converted (Component - HDMI), does not cause this problem, only a source that is connected to the NAD through HDMI.
Also, this does not occur when DSP is turned off, everything plays fine, indicating that the cables are fine (I did test other cables to rule this out) and that the issues is with Audyssey (possibly with HDCP).At the moment I'm keeping DSP off - not sure if the "pop" will damage any of the equipment.
Thought I would let you know since I know that you are continuously working on software issues as all others are in the business.
