This past week I finally became frustrated enough to search to find others sharing my experience. That is when I found this forum and the great information. As far as I can tell, my frustration could finally come to an end with a firmware upgrade. Could someone PLEASE send me 1.32, 1.34 and 1.36 firmwares for my T785. YES I understand that I only require one and most likely the one necessary would be 1.34 but I am asking for all 3 just in case... I am hoping that once I resolve this LONG ENDURED issue I can then tackle the REMOTE HTRC 1 custom programming so that I can eliminate the PLETHORA of remotes scattered across my table... LOL
Thanks again in advance for your help in this... Steve.
I'm not sure that a firmware update will solve your issue. It depends on what issue you are having. I have two dropout issues. The first only occurs when playing high-res multi-channel audio with Audyssey turned on. With this issue I will lose all sound for a duration of a second or more during playback. This doesn't occur at the beginning or end of songs or tracks, but could happen any time. I've worked with NAD support on this, and have tried multiple firmware versions, but none of them have resolved the issue. I believe it is a hardware problem, as I have read earlier posts in this thread that indicate this (http://www.avsforum.com/t/902321/the-nad-t775-t785-avrs-w-hdmi-1-3-thread/2910#post_18475680
), and have also seen many cases where replacing the MDC boards resolves the issue. My receiver (T775) is currently on it's way to an NAD service center because it appears that the AM200 board has now completely failed. Whenever I power on my receiver I get a display message that says "Check DSP Board" and no digital audio playback is possible. I'm hopeful that whatever hardware fixes get made resolve this issue.
The other dropout issue I have, which is similar to the one most recently reported here is the cutting off of signal for the first few seconds of a track when playing through digital inputs. Firmware 1.34 and higher mitigates this issue for me, but does not completely resolve it. According to my communications with Lenbrook (NAD distributor for North America), they are aware that 1.34 doesn't completely solve this problem, but that the cutoff has been reduced to 100ms or less. I'm not sure if you are in North America or not. If so, the best place to get the firmware is from Lenbrook directly. You will need a windows PC and a serial cable to do the updates yourself, but it is very straightforward to perform.
Also keep in mind that your receiver has a two-year warranty if purchased new from an authorized NAD dealer in the US. My advice is to report the problem immediately and get NAD/Lenbrook to commit to extending your warranty until the issue is resolved to your satisfaction. Also be prepared to deal with a lot of deflection, such as blaming your downstream components or HDMI cables. My experience with NAD/Lenbrook has been positive overall, but these things did happen to me, so I'm just sharing them so you will be prepared.
I'm really mixed on my feelings about the NAD T775. On one hand when it is working it is simply amazing. I use Polk Audio LSi9s and LSiC for my front stage and these 4 ohm speakers are known to be hard to drive. The NAD receiver mates well with them and I love the combination. On the other hand the issues I've had and the lack of a fix from NAD is disheartening. At this point I feel that I may have been able to get the same or better results for the same money, with a lower priced AVR used as a pre-amp/processor and a separate multi-channel power amp. I haven't given up on the NAD yet, and hope that when it comes back to me in a few weeks, it lives up to the accolades that made me purchase it in the first place.
Good luck getting your issues sorted.
