The NAD T775/T785 AVRs w/ HDMI 1.3 Thread! - Page 136

nosferatu -
The materials in the volume knob break down and/or corrode if it doesn't get used enough. Luckily, it only costs around $30-40 to fix. I didn't fix mine because I rarely use it. Tip for others - every now and then just turn the knob around a few times. Supposedly this will keep it from developing this problem.

Update on my audio drop out issues - I was watching Looper on my BDP-83 and now I was getting occasional popping noises. Switching the resolution to 1080i resolved this but I'm not too thrilled about having to do that. I have yet to swap hdmi cables but from what others said I'm not too hopeful that this will solve the problem. Upgrading to vm150 seems to be a costly solution. I should have just stayed on the old firmware!

Nosferatu... Spray some Deoxite in the control reastat and it should be all good...

Hey, can anyone hook me up with V1.38? I sent Hairdawgg a PM, but got no response (he doesn't look like he posts much, so maybe not online here often).

Will this upgrade the DSP, VID and UART as well? This is where I'm at right now...

MCU V1.28
DSP V1.04b
Vid V1.01
UART V1.05

Thanks folks!

SimplySound you sure that's the issue ? i read somewhere here that was some kind of board but i will give a try does the knob comes out ?or do i need to go from inside of the unit .

thank you

Well not sure, but being an Audio Guy, I know deoxit will clean the contacts in something like a volume control. I have a hard time believing it is in a controller board and not in the reostat. i think Dylan has it nailed, if you don't use the volume knob and live in a high humidity area (like Sarasota), the contacts in the reostat will corrode and it won't adjust the volume.

When I get my unit in, I will pop the top and take a look.

Stay tuned!

The mythical MDC AM250? This was from an annoucement back in 2010...

If you look on NAD's site there isn't an AM250 listed. So question is; did it ever get built and released. Does anyone have one? What features over the AM200 does it provide (description above sounds like the AM200)?

Interesting!

Thanks to Nosferatu for gettting me updated to V1.36. Seemed real easy to do. Surprised NAD doesn't make these updates more accessible, of course with a disclaimer that if you mess it up, you own it!

I would like to get V1.38, so PM me if you have it available...

Also, the update process answered my question that the update does update the DSP/VID and UArt Code as well!

Thanks folks.

Does anyone know, or has anyone heard, any word at all about NAD putting any additional formats into their Pre/Receivers? Things like either Audyssey DSX or DTS Neo:X? I am interested in getting my home theater beyond 7.1 and currently have, and have been VERY pleased with an older NAD receiver so I would love it if they would catch up on some of these formats.

Thanks in advance guys!

I am just getting my T775HD (VM100/AM200) setup and running. I purchased it in June 2011 when Audio Advisor was clearing them out.

I'm still working on the detailed setup, but for now I need an easy way to bypass the NAD when my wife and kids are watching TV or a movie.

My plan is to buy a monoprice 1x2 HDMI splitter for each source component and send one output of the splitter to the NAD and the other output of the splitter directly to the TV.

Any gotchas to watch out for before I buy the splitters and HDMI cables?

Thanks,
Kent

ps according to one monoprice reviewer, their 1x2 HDMI splitter only works if both output connected devices are on. if you want to be able to leave one of the output connected devices off, you have to use the monoprice 1x4 HDMI splitter. I want to be able to leave the NAD off, so I suppose I will buy the 1x4 splitter even though I don't need the extra outputs at this time.

I received the VM150 and VM150X today. Put it in, and the audio dropouts are gone. Works great. Firmare V1.38.
The picture quality is IMHO not as good as before, the VM200 "smoothed" it a bit and it looked better that way. Now it is a bit grainy. Player is a Oppo 105, seems I have to tweak the settings.
Someone interested in a VM200? Works great as long as you don't feed 1080p60.

Thanks Mungam and CYE for the V1.38 update. I'm putting that in tonight. Spent the weekend getting my system dialed in and the NAD just blows away the Maranz SR6006 sound wise. No comparison needed!

As for my Sony Bravia TV, with the VM100 I had to run a TOSLINK cable. I guess ARC is only supported on the VM150. Other than that, everything seems to be playing together real well. I'm using a Sony BDP-S780 and it seems happy. One thing I did notice, is I can't seem to use "Enhanced Stereo" for Music Blu-rays...it seems to only provide "Surround Features" or Direct.. I like Enhanced Stero over Surround sometimes... I guess it's just me.

That's good to know Magnus. I guess I'll have to get the VM150/150x. I thought you had the Oppo 103. Did you return it for the 105? And, if so, aren't you really supposed to use the analog outs on the 105 rather than hdmi, or are you running both?

With the 775 HD you should be able to get sound via HDMI when you switch to 1080i. At least it worked for me.
The surround modes depend on the source, e.g. if you play two channel DTS you have only Stereo or DTS Neo.

I HAD the 103 for one day and upgraded to the 105. I am running HDMI and analog. Now I have to see what sounds better: My old NAD T587 via HDMI or Analog, or the Oppo via HDMI or Analog. I have a special setup: The T775 only drives the Surrounds, the Mains go to a Rowen Active Driven Stereo System consisting of a Preamplifier -> frequency crossovers -> 2 Stereo Power Amplifiers (Low and Mid/High) -> Speakers. Unfortunately the T775 doesn't have a direct input for the power amplifiers, so have to use the additional two stereo amplifiers.
For Stereo listening I bypass the T775 and go directly to the Rowen Preamplifier. IMHO the stage is a bit wider when bypassing the NAD, but for a Surround system and all the features it has, the NAD is really great.
BTW: The Rowen system is made by one of the founders of NAD. He is the NAD Importer in Switzerland. Their amplifiers are stable down to 0.5 Ohm and have negative output impedance.The speakers are bipol for a extrem linear frequency.
Here is a link to their technology: http://www.rowen.ch/en/tech.php

Now there's an idea. Hey NAD, if you are listening... yanno that mythical AM250 module? Include an Analog AMP IN connection so you can feed a dedicated Audio Preamp into this thing!

Thanks Mungam for the Rowan Link. That looks like some trick kit! Like the Quad-Active stuff. That is L'Absolute!

Hey CYE, you were wondering about my fans. They are uber-quiet. I can't even hear them unless I put my ear right up to the vent. Like I said, you had me concerned about if they were operational, because I hadn't ever heard them. They are functional because I can sense forced airflow coming through the vents.

If you have noise it may be a fan bearing going bad or a fan blade rubbing on something! Hope you can figure it out!

Oh and yeah, got V1.38 in place and all systems go! Thanks!!!

I'd appreciate a link to 1.38 too please.

Thanks.

I have to admit, after listening to some FLAC files today and making sure that the Oppo Analog Out and Nad Pre Out have excact the same volume level, it is very hard to hear a difference. The NAD performs great.

My T775 is going back today to see if I can get this fan issue sorted - it's so bad I couldn't run Audyssey due to the ambient noise level. Gutted. :-(

Sorry to hear that... hang in there CYE, hopefully they'll get it running good as new! Let us know how it goes.

Yeah, I think the DAC's in the AM200 are probably some of the finest you'll find in any audio component. But I haven't found any real information on them other than it is some sort of "Dual-Core Burr-Brown" chip.

I have yet to compare my Cal Audio Labs Icon MkII Analog Output to using it as a transport. It uses two 20bit Burr-Brown PCM1702 DACs. The NAD I believe is 24bit at 192KHz, but does anyone have an actual component spec?

Was your fan noise constant or does it come and go? I have a T775 that I have had for almost 3 years now and it has started having some fan buzzing, but it does not stay that way for extended periods of time. It can happen when the receiver is first turned on, but then will stop after several minutes. I have been meaning to open the case and see if there is just a bunch of dust in their to blow out, but have not had the time yet.

You got your Sony to do ARC with Nad? What Sony model? How did you setup the tv and NAD? I have the Sony 929 and it can't detect the Nad over the hdmi. Thanks

guys i'm seriously contemplating getting the NAD T757 / T777 or a Pioneer SC 68. I had a question for NAD avr owners. What made you choose the NAD avr over another brand avr ?

Mark,

It was constantly there, like an old noisy PC! So much so that I couldn't run Audyssey, due to too much ambient noise. I'm hoping they can sort it, and possibly even send me a replacement.

Cheers, Doug. I'll post back when I have some news.

I dunno if it counts for much, but to my ears the NAD sound is far superior to anything else I've heard for 'realistic money'. I've had Meridian 568.2, Denon AVC-A1SR, NAD T168 then went to a Denon 2807 and missed the NAD sound so much I went for the T775 a couple of weeks ago. The NAD sound is hard to describe, but the words huge, controlled, detailed yet warm, powerful and enveloping come to mind. It just sounds 'right'. The Meridian did too, but at a significantly greater price point (especially when you factor in power amp costs). I also really like their EARS DSP, it's great for running your 2ch music through a multi-channel system - not to be confused with crappy DSPs like Hall, Church etc. I think it's right up there with Meridian's Trifield.

If you haven't heard one, deffo get a demo, I think you'll like.

HTH

Since the Official NAD T175 thread kind of died last summer, I jumped over to this NAD thread. I chose my NAD T175HD pre/pro because of my experience with my older(2004) NAD T773 receiver. It is by far the best sounding multichannel receiver I have ever heard, so much so that it would give some midfi multichannel seperates a run for their money, IMO. Very powerful and stout(53.00 lbs) receiver with a huge soundstage and very detailed.

I was exhaustively searching for a used T775 or T785 in my price range to take advantage of HDMI and room correction and stumbled upon my T175HD pre/pro for $1000.00. Hard to pass up that deal for such a great price. The T175HD and my Acurus A200 and A200FIVE amps sound incredible driving my Klipsch RF-63 system.

Other mass market AVR mfr's do offer more modern bells and whistles in their receivers but for musical purity and fantastic HT processing, the NADs are hard to beat. Again, my opinion.

Bill

Those are the most accurate choice of words to describe the NAD sound. I don't use the EARS DSP much but the Enhanced Stereo mode really makes everything just come alive. I like the way you can select which channels you want included with the Enhanced Stereo setting. I have yet to go through the process of setting everything up with Audyssey MultEQ XT but will get around to it someday. It sounds great right out of the box.

Bill

Will,

Seriously, take the time to get Audyssey setup and right - it makes all the difference. And definitely check out EARS with a proper critical listen - it uses the centre and surround channels brilliantly, way better than PLII Music etc. Meridian's Trifield is very widely regarded to be the best at this, but I think EARS is 95% of the way there. NAD don't really make much of a deal of it, but I think they should - it could be a great selling feature IMO, especially for people who value their stereo music collection and would like to take advantage of their multi-channel system.

I've just realised I called you Will, and you signed yourself off as Bill - apologies.

No apologies needed. I am a William but am commonly called Bill. I have a friend that I have known for over three years that also addresses me as Will even after nicely correcting him many times over the years. He just forgets.
