post #3811 of 4288
I got my 785 with the AM/VM 200s upgraded to firmware 1.34 and it is awesome. I have no audio cut off at the beginning of tracks from any digital source at all. I am in love with 785 all over again.

Does anyone know what the unused Daughterboard ports at the rear of the VM150 + VM150x are for?

Isn't that nice. I have had my T775HD since last summer and while I liked the sound, small things like this was annoying me, but I knew that NAD will come through with a firmware update. I think we should send a thank you to NAD for coming through. I have previously owned HK and now NAD and both of them have great customer support dept even though I think HK moved theirs overseas!!

I indeed got the T763 back from factory repair, fairly shortly after the local repair shop finally gave it to the NAD rep. Everything went fast after NAD was in charge. They replaced a bunch of boards, they tested it over a week-end to make sure it was not a fire hazard and it still runs now. While it displays the noise same problem as before, this may turn out to be something not being the T763's fault, like my subwoofer causing interference. I shall see how my investigation turns out.

Good luck guys with the T7x5 line.

You mean what is the LAN port for ? The marketing argument says: "Ethernet Port allows network control of the AV receiver"

Unfortunately, at moment the current firmware doesn't permit to use this feature. I contacted NAD and my local NAD dealer and confirmed me : "We have to wait on a new firmware update"

What would be nice is if we can get features like AirPlay or Internet Radio, Pandora, etc. These are just services that run on top of TCP/IP. Once the infrastructure software is there, everything else on top could be done! Even future firmware downloads, however, I doubt it.

I work on embedded software/hardware and have implemented TCP/IP/DHCP/SNTP/HTTP, etc for a small hardware with minimal OS support. Now we can update our firmware through http and ftp, as well as perform all configuration through it.

We should even be able to use an iPhone, iPad, Android or other devices as remotes and even perform calibration. This would come in handy for Audyssey since my projector makes some noise. This way, I can leave the projector off while I do the calibration.

I can dream

cool! I use three NAD C272 amp's (150W X 2 each), combined with a Yamaha RX-V2700 receiver (as pre-pro), and a Denon DVD-3930CI player. It's a sweet sounding set-up. However I've pre-ordered the new T175 pre-pro. Can't wait to hear difference between NAD and Yamaha pre-amp.

No, on the VM150 card itself there is a port for the VM150X and towards the back of the card there are more daughterboard slots. I'm guessing this could be used for additional analog upscaling features like the VM200 has (but thats a complete WAG).

Would this advice about microphone colours also apply to older T775s that have been upgraded with the VM150/AM200 boards? Just got mine upgraded (plus some other fixes)

That's a good question. I would have assumed that it depends on the dsp they have which will depend on the mdc card. But you might want to check with NAD.

Anyone seen if, other than the wattage, there are any substantial difference between the 775HD2 and the new 777 that is coming out? Better Audyssey or anything like that?

From what I saw, it has the same AM200 card and says audyssey multiEQ XT. So no difference. I think they changed the face plate and lowered the amp. This is kind of unfortunate because they are coming under typical CE pressures of constantly upgrading. The beauty of mdc is kind of watered down. I hope NAD will still release new features in addition to bug fixes through firmware updates. I know this does not give them immediate financial incentives. But at least more loyal NAD owners. For example, my NAD T775HD with an upgraded vm150 is perfect right now but if they do support multi eq xt32 in the future may be it could be a firmware update. I don't mind not having an old face plate. I think if mdc is to become relevant NAD has to convince owners that card upgrades are the way to go and not whole units. If more people did that may be the mdc cards could come down in price too.

Guys,

Planning to get the NAD T775 this week.
Is it capable of playing FLAC files through USB and what disk format does it recognize coz I'm planning to play FLAC using my 500gb portable drive.
Also is the T775 HD capable of streaming FLAC audio files from DLNA devices like android smartphones?

Thanks a lot :-)

If that is important to you, you are going to be disappointed. The T775HD2 comes with the AM200 and VM100(3D version) cards. There is no ethernet on this. There is a VM150 and VM150x upgrade cards which the VM150x has ethernet but the software work is not yet completed. NAD has not even advertised what it will support yet. I would say get a dedicated streamer for your FLAC files such as a WDTV, or one of the other ones. YOu can still use the DACs on the T775 which are very good.

I use my computer directly connected to the T775 through optical. I also use an AppleTV for another room connected to my NAD T744. Works great and I don't have to worry about new audio formats not getting supported, etc. The AppleTV is only $100 while the T775HD2 is $1999 or so - if I am correct.

Well I just got my 785 back from the shop and after a 90 mile roundtrip, set everything up and the right surround channel is still not working! I found if I crank the surround +6db, I will hear some crackling from that speaker but that's it. Of course, if I swap the left & right surround speaker wires, it follows to the left speaker not working. Guess I should have had them show me it was fixed at the store (who sent it to the NAD auth repair shop). And they had it in the shop for 2 months, supposedly waiting for a part (which I don't know what)!

One other thing... I also had them add the vm150x card. The salesman did say I was brave to do an upgrade right after it getting it back but I didn't want to make that drive again. Anyways, I still have a Toshiba A35 HD DVD and I connected it to hdmi-4 on the 150x card. Tried playing a dic and it kept stuttering (pciture and audio would blank out for a second and then return). Tried a different hdmi cable, no help. Switched the player to send pcm vs bitstream,. no help. Tried another disc... Then put it on hdmi-3 which had my Oppo 93 on it and it plays perfectly. The Oppo plays fine on hdmi-4.

Anyone else have a HD DVD and vm150x to see if they see the same issue?

Upgrading from Audyssey XT to XT32 would require more powerful processing hardware, not just a firmware update, so don't expect it to happen.

I have an iBuyPower i7-930 gamer computer with an ATI HD5770 video card connected to my t785HD with AM200 & VM200 cards and mostly love it. I originally tried using HDMI for both audio and video but experienced the same sound turn-on delays (skipping 3-5 sec of track beginning) so I wound up using optical for the sound and HDMI for the video.

That's until I upgraded the firmware from v1.23 to v1.34 last week. Now I'm running full HDMI between the computer and the t785HD with no issues whatsoever. My next step will be to switch the cable box (SA 8300HD) back to HDMI and see if the problems have disappeared there too.

Problem 1 was the cable box would experience strings of audio dropouts on both HDMI and component/optical which required changing the channel to fix. That's appears to be fixed with v1.34, at least for component/optical. Problem 2 was that the cable box would "lock up" with HDMI. The picture would shift side-to-side continually and the sound would cut in and out. The only fix was to reboot the cable box; something I would have to do at least weekly. Switching to component fixed that but I'm hoping v1.34 fixed that for HDMI too - I'll test that when I get the energy to get behind the system again.

I can also report that the firmware upgrade went very smoothy. I used my older laptop with RS232 M-F cable. The interconnect doesn't require a null modem, just a straight RS232 cable. The upgrade software auto-negotiates the connection so you don't have to mess with Com Port settings. After each step, it restored my settings, including Audyssey, so at the end everything was retained. I'm very happy with the results so far!

Yes Phil, I've had exactly the same issue with inputs on the VM150x. I had my PC connected to HDMI4,5 or 6 and syncing issues would occur. Placing my PC on HDMI 1,2 or 3 would fix the issue.

I also tried a DVD player on the same inputs and the issue was still there (although not as frequent).

I have recently purchased an OPPO-BDP93 and it is working without issue on HDMI4. I've also upgraded to FW1.34, so I couldn't tell you if it works because of the firmware upgrade or the BDP93. I'll attach my PC to HDMI4 to see if it was the FW tonight. NAD are aware of my issue, as I sent them some information towards the end of December.

I'm still on v1.32.

thanks, glad it's not me. I was thinking maybe the hd dvd player was going bad.After I got the vm150 and lost the 4th hdmi, I tried a hdmi switch and the hd dvd player also had problem connected thru that but the Oppo was fine. I assumed the switch was at fault and moved the hd dvd to component video. Now I lost that option!

Since many of us have gotten results with the firmware 1.34 I suggest we send a thank you email to NAD. I am sure they will appreciate it.

Actually not:

"MultEQ XT32 increases filter resolution 32-fold using an innovative new signal-processing algorithm that does not require any additional computing power."

That's what I thought too but I am sure licensing costs might discourage a free firmware update. What would be nice is a paid software upgrade if a free one is beyond their scope.

I have the T785 with the AM200 and VM200 installed. Previously I had 1.24 installed, but upgraded to 1.34 myself.
I had big problems before with audio drop-outs, no sound at the start (appr. a second) when I was playing SACDs. I assume it was some HDMI/HDCP problem, but I would not know that.
What I do not understand is why NAD is not telling us what the Firmware fixes.
After the upgrade it's like I have a new Receiver.
I haven't done a test, but I think that the SQ is better than before. It just sounds better. (it may be an illusion)

So I am very happy that I made the firmware upgrade.
post #3835 of 4288
I'm pretty sure the SQ thing is an illusion, but I'd go along with the sentiment that the unit with 1.34 installed is how I'd wished the unit had been from the start.

My display does show white noise when switching inputs now, but if this is the price to pay for having no audio drop outs then I don't care.

NAD is like most electronics companies in regards to fixes, if they told us what it was that firmware upgrades fixed, then they'd be admitting to the problem in the first place. Just be grateful that the issues have been fixed. I wish it wasn't that way, but I would imagine that this is more of a commercial issue. Some companies have embraced a free-er exchange of information and it is commendable, but there are overheads associated with this practice.

NAD if your listening, then the paid MultiEQ XT32 (if it is even possible) is an interesting proposition.

From Bob:

Yes the new HD models use a different Audyssey HD Mic, denoted by a Silver connector, versus the Gold connector of the Non- HD Models.

The new Mic is available at NAD Parts; 1-800-263-4641 ext. 4383.

I have not been advised what the difference are between the 2 mics.

If Audyssey Calibration runs correctly on your unit with the 'Gold" MIC, then I would not be concerned about updating it.

Hi Phil,

I further researched your question on the Audyssey HD Microphone.

The supplied microphone comes directly from Audyssey and has a minor difference in response levels. The microphone supplied with our T 785HD has a 2kHz difference from the earlier microphone made available with our T 785 (non-HD). The T 785HD's firmware is also different as it includes the new microphone correction curve."

I hope this inforamtion is helpful.

Best regards,

I wonder if that means those of us who upgraded to v1.34 should get the new mic?

NAD Electronics Hi Phil, the new microphone has a 2kHz difference. You don't need the newest Audyssey microphone for optimal results, such a slight difference in response is nearly inaudible. The latest microphone does not come with our AM200 MDC module.If you have any more questions, please feel free to open a ticket in our NAD Salon (http://nadelectronics.com/salon). -SW

Got my T775 back with the AM200/VM150 cards, and it arbitrarily, or possibly because of an obscure settings adjustment, decided not to give me sound from the speakers for a few days. One factory reset later and I was able to perform an Audyssey calibration. With the old mic. So it works with the gold one. Now as to the accuracy of those results I will have to wait and see. The first thing I did after the calibration was set up the sources and then listen to some very loud doom metal on vinyl (so 2-channel analogue), and then sleep. I guess over the weekend I will find something explosion-y on Blu-Ray to test it on. I probably won't be able to provide comparisons with the old Audyssey sound, because my unit had become so unreliable in the months before the upgrade/repair I was factory resetting every couple of days and gave up performing calibrations. I am hoping that the combination of repair/cards/firmware will draw my four-year quest for a stable NAD receiver experience to end.
