Official NAD T 757 AV Upgradeable Surround Sound Receiver Thread - Page 3

Update regarding Delay issues with digital music formats through Digital in ;
NAD customer support has been fairly good in keeping me up to date. It seems to take a very long
time but they informed me recently that they are beta testing a firmware update that should address this
issue.
Let's hope they manage to fix it.
Besides the delay issue, I am very happy with the sound quality of this unit.

I have the same delay problems with spdif from my TV.

Have you fixed the problem?

I have received a beta firmware update for the T757 from NAD. It has resolved the issue for about 99.9% (meaning you will not hear it unless you start lookin for it, but this might be the case with many devices). MP3 / FLAC connected through optical now work fine. I have not detected any issues with HDMI either (although I have not tested it prior to the update). Not sure about spdif, I would report the issue to NAD Customer Support and inquire whether the beta firmware that is being tested might resolve it.
I have given my feedback to NAD so assume they will publish an official update in the near future.

Mine started doing this today, I've only had it a few weeks.

I have a 775 and it was doing this for two days last week. It's been ok since. I would suggest to give NAD a call because they said it was the first they heard of this issue. I know in the 775/785 thread a couple of people mentioned it also. NAD suggested a power cycle and if that doesn't work a factory reset. Luckily I didn't need to do a factory reset because it seems to have resolved itself, for now.

I've just registered on their site and posted a support question. Hopefully they'll have heard of the issue this time

Glad to hear yours has stopped troubling you for the time being.

Once it started it was doing it every few minutes, pretty depressing (especially when it jumped to +12db). I gave up in the end and did something else.

Edit: Well that was a waste of time. For the record: NAD will only answer technical questions from US citizens on their web site, and they'll take two days to tell you this.

I got my faulty T757 replaced with a new one yesterday.

I was pretty surprised when my Sony TV said an external amp had been connected when I first switched it on, first time I've seen that.

It turns out the new one supports HDMI Audio Return Channel and Consumer Electronic Control.

There's also a new HDMI item in the setup menu.

Haven't had a chance to play with it much yet, but pretty happy so far.

I've been thinking about picking up the NAD T 757 (I can get one around $900), but I'm looking for opinions. I'm looking for a new receiver for two main purposes. One is to add HDMI connectivity in order to natively be able to process the new audio formats, and second is that my Rotel is developing some quirky volume control issues.

In the interest of full disclosure, here is my current setup.

Rotel RSX-1056 receiver (non HDMI), and Rotel RB1080 amp (200 watt per channel)
Direct TV HR34 HMC
Pioneer ELite bdp-51fd blu ray, Toshiba HD-DVD player (I use for regular DVD's)
Panasonic TC-P54V10 plasma TV
Rega Turntable

Main Speakers: Vandersteen 2ce sigs(driven by Rotel 1080 amp)
Surrounds: Vandersteen 1c's
Rear surround: Polk audio RTi A3
Center: Vandersteen VCC-1
Sub: Vandersteen V2W

I use my system for about 80% music, and 20% HT. My main music source is actually a Windows media center PC where I rip all my CD's to native WAV format. This is connected to my Rotel via digital optical cable. I tend to listen to my music in a mode called seven channel stereo, but I disable the center channel. I think I've narrowed my search down to the Marantz SR5007, Denon 3313CI, and the NAD T 757. My setup is pretty simple, and since I live in the country and my internet is terrible I don't do any streaming audio stuff. I don't need gobs of power since I have the big amp for my mains.

I think the Denon has more "stuff" than I actually need, but the Audyssey MultEQ XT might be useful since my listening room isn't a perfect environment. The Marantz SR5007 also has Audyssey MultEQ XT, but again I am not sure how useful this would be for me. The NAD looks like a very minimalist and audiocentric choice, but it is lacking on many common features. I'd be interesting in hearing anyones opinion on the NAD vs Denon vs Marantz. Thanks

double post.. Sorry

Now released T757v2
I wonder whether is it possible to make an upgrade to version 2 for existing t757?

MustangJeff: What did you end up going with? You're looking at essentially the same choices that I have - I'm setting up my first surround system and my setup is similar (Vandersteen 1C as surrounds, 3A Signatures as front, eventually a VCC-1 center, and sub [not Vandy but good]). I've got an NAD stereo receiver that sounds great and I like sticking with what I know, but the Marantz looks tempting, as does the Anthem MRX and the Denon 4311. Did you end up with the T757?

whats the difference and whats updated...?

My v1 was replaced with a v2 a couple of months ago.

Other than the menu looking slightly different, the only real change is support for HDMI ARC & CEC.

It might be my imagination, but I didn't think the "enhanced bass" speaker setting worked on the v1 unit.

thanks for that... have you contemplated getting the AM 200 MDC Audio Module to get the Audyssey MultEQ XT ?

i'm wondering over T757+AM 200 vs T777 ( Built in AM 200 )

I am getting a T757 shortly. WIth the new ARC support, how do you specify the ARC as an input in the source setup menu? Is that part of the new new HDMI item in the setup menu that you reference.? It is obviously not in the original manuel. I assume you need to specify a new source in Source Setup to use the ARC input. Thanks.

I'm not sure why they haven't made the V2 manual available on their site, the PDF came on a CDROM in the box.

Here's the section on ARC;

Thanks. Turns out I never had to set it up. The Internet was too unreliable to stream anything reliably. I tried it from the TV and from an Oppo. Neither worked I am doing this for a friend, so will probably go back and see if we can get better response. He says that it is pretty common to have bad connectivity on Sundays. If we can get some reasonably speed, then I will go through the ARC setup. Thanks again.

Hi dear Nad owners,

I just got a brand new NAD T757. The look of this avr is so clean, I love it already !

Unfortunately for me there are some strange issues that drive me mad. Can you guys check if it is the same for you ?

1) My Panasonic TV is connected with the "HDMI Monitor" connection. I can't see the OSD menu after the NAD is powered on unless the receiver get a HDMI signal from one of the 4 hdmi in (in order for the first signal to work I have to power on and off my dvd player a few times otherwise I don't even have an image on my tv and of course no OSD menu)

Is any of you able to get access to the OSD menu without any other HDMI material powered on except the TV ?

2) As said it means also I have a nightmare to get either my computer (HDMI) or DVD player (HDMI) to be seen on TV if conected to the NAD, I have to change "sources" hundreds of times and power-on - off computer and dvd-player.


3) My music is coming from my pc to the NAD with PCM audio. Unfortunately the NAD don't output any of the digital music into the zone 2. So for now I can listen only to the radio in Zone 2 ... I really wanted to use the internal NAD DAC to enjoy music in the kitchen too ... Do you experience the same or are you able to get any of your digital audio source (stereo PCM of course) to Zone 2 ?

4) I already experience the 2 or 3 seconds skip of the beginning of each audio track send with HDMI & Toslink. (Hope i will be able to get a firmware uptade, but first I have to know what's about point 1 and 2)

EDIT : 5) I forgot to mention the NAD produce noise when it is on. No matter if it is working, only by staying On the unit produce noise.


Have a nice day,

Lobotom1.
Edited by lobotom1 - 1/13/13 at 3:45am

what kind of noise ? could you describe it ?

Lobotom,

I used to have that problem. Turns out the HDMI cable I used from the computer was faulty. So check out if all ur cables are ok. THe noise thing doesn't sound normal. Please describe the noise

Now I have a question

When listening to music I come in analog from my external DAC. I listen to music in stereo mode, because as you all know this option lets me enjoy music with the subwoofer on. With analog bypass the sub is dead. Now, does anyone know how the NAD processes the signal in stereo mode when an analog signal is input? Does the whole signal get converted into digital and then pass thru the NAD's internal DAC to convert it to analog once again? Or does NAD divide the signal in two, one remains analog all the way, and the other is converted into digital and sent to the bass management? I can't find this info anywhere on the internet. Can someone help me out?

Hi folks,

New on here, but looks to be a very informed group...

A very good friend of mine has just recently purchased the T757. 700 dollars this past boxing day....seems to me he got a very good deal. So far he seems quite pleased...he is running in 2.1 at the present moment with Totem Sttaf spkrs and a Paradigm Sub. He is however having an issue getting audio from his satellite receiver. It's an older unit (pre HDMI) so I suggested he use the optical for the best connection available, but for some reason we were not able to get any signal whatsoever....not sure if possibly I was doing something wrong in the menu setup, but I will say that I can't seem to hear that click I typically feel/hear when plugging the opt cable into the back of the NAD...it just seems really loose therefore I tend to think the connection is the problem.

Is anyone here using opt cables into the back of theirs?

I told him to hurry up and get a new Sat rcvr with HDMI

Thanks for any insight...

Cheers,
Jethro

Hi everyone! I live in Sweden, and am new to the forum. Bare with me if my English not always is "top notch"!

I purchased a T757v2 two weeks before this Xmas. A great piece of equipment! However, there are a few issues with the T757. I state the rest of my audio/video-system for reference, all devices are connected to the receiver:
-Dali IKON 6 Mk1 front speakers
-Dali IKON 1 Mk2 back speakers
-Dali IKON Vocal 2 Mk2 center
-Dali IKON Sub Mk2
-Thorens TD318 MkIII turntable, through a NAD PP-2i Phono Preamplifier
-Panasonic TX-P46G15e plasma television set
-Motorola 1910 ATSC tuner
-Other devices connected to the T757: gaming systems Wii (component + analog audio), Wii U (HDMI), PSTwo (component + optical audio), PS3 Slim (HDMI)

The issues at hand:

1. I have noticed that when I turn on the T757, it feeds all speakers in the system (except the sub woofer) and the headphones with a high pitched noise, like a high frequency “buzzing”. The noise is low in volume, but quite noticeable.
It is not affected by changing Listening mode or adjusting the volume. However, when I change source on the receiver the noise disappears. Most often it is enough to change source once, but sometimes I have to do this operation two or three times until the noise disappears. I executed a factory reset, but no luck in solving the matter
I have read that power cables that run too close to speaker cables might have a negative effect, so I have tried only running the receiver and the front speakers (no other equipment in use at the same time), but no effect on the described noise.
NAD suggested I should exchange the receiver and get a new one from the dealer, which I also did. The problem is however present in exactly the same manner on the new receiver.
Does anyone recognize this problem? Suggestions?

2. I also noticed that the TV-display sometimes shows a uniform, yellow-tinted screen instead of an actual TV-picture from the ATSC tuner.
This occurs when:
- I start the ATSC tuner before turning on the NAD T757, or
- when I have been watching TV through the ATSC tuner, switch source on the T757 to for instance CD-player, and the again returns to TV through the ATSC tuner.
I solve this problem by switching the ATSC tuner off/on, which causes the yellow screen to disappear and then the display once again produces the expected visuals (TV-program).
The ATSC tuner is adjusted to output 720p and digital sound. It is connected to the T757 by HDMI.
Any suggestions on solving this matter?

Any ideas or suggestions are must welcome!

I only use optical for audio from my PSTwo, but it works just fine. Have you tried exchanging the cable itself? Or tried out one of the other optical slots?

Hi Folks,


Thanks to the great info on this site, I recently took the plunge and purchased a T757 to upgrade my HT system.

I"m very happy with it so far. Mostly with the 2 channel music performance. I was overjoyed the first time I played a CD after hooking the system up and referencing how my speakers sound vs how they were with my old Denon. Spectacular!


I have a general question. How do you all think the performance of the AM100's DAC is for music listening? Is it comparable at all to the MDC DAC module they provide with their 2 channel hifi systems? Is looking at a nice dedicated external DAC going to be a big enough upgrade?


I typically am doing most of my listening via streaming to an AppleTV module via digital in, so almost all my sources are digital.


Thanks again!

@rodjon

I just relaced the NAD t748 because it had an annoying audible pop between cd tracks when connected through the digital input. First NAD, but I've fallen in love with the sound it produces - so I tried my luck with the more expensive (but even better sounding) t757.

As soon as I plug in the device, I hear a very low noise humm (still on standby) - slightly concerning but not annoying. When I power up the device I get the same high frequency noise through all speakers regardless of listening mode. Only when I change to the ipod-in source, the noise stops.

Aside from this, I get the 1 - 2 second delay instead of the t748 pop. From the frying pan into the fire...

ATM my dealer is looking into both issues. From what I read in this topic, the delay will probably be resolved by applying a firmware update. Though I fear the t757 will need to be repaired for that noise issue - I will try to have it specifically sent for repair since you got two similar issues with two new receivers already...

On a smaller note: does anyone else feel input through the remote is delayed when setting up the machine through the osd? It feels downright awkward compared to setting up the t748 with the same AVR4 remote and a similar OSD menu. It makes you feel you have to press the buttons with force and realy tests your patience...

Edit: It appears the NAD distributor already sent a replacement unit to the dealer - will go and exchange receivers next thursday. We agreed to test the receivers at the dealer to be sure the high frequency noise issue is resolved. I hope it already has latest firmware on it as well.

On my NAD T775HD, if I set the mode to analog bypass, it stays analog all the way and no bass management is applied. If I set it to something else, then it goes through D/A, bass management and A/D.

Sounds good, fingers crossed! I hope they sort it out, and please keep me posted! If you were able to solve the problem, I get new hope in fixing my 757 as well!

Sorry, double post... Deleted.

Well.... I changed receivers today, and since my dealer stressed that the NAD distributor checked the device before sending it, I took it home.

The good stuff:

• Standby no longer produces any sound, humm or whatever and my remote is more responsive (only the down arrow doesn't work well)
• 1 to 2 seconds delay issue through digital in is resolved. The distributor probably updated the firmware - no issues there as the DAC muting between tracks is no longer audible
• Last source that was selected is now remembered

The bad stuff:

• Still a high frequency noise upon startup.

I have been checking the settings of all Sources as somehow not only the iPod in, but also Source 4 now removed the noise.
It appears that when you select any video-in for a source, it stops the high frequency noise when selected.

I verified this by setting Source 1 to no video, changing it to the various video-in settings and "rebooting" the t757 each time. When video-in is disabled for a source, and that source is active upon starting the receiver, there's a constant high frequency buzz through all speakers. When video-in is set up for the active source, you still hear the noise - but it is cut quickly after booting the receiver. Same as changing to a source that has a video-in.

Of all video-in options, HDMI didn't help to fix the issue - there's still that continuous buzz. This is concerning as I plan to use HDMI in the near future. I am still saving for a nice screen and blu-ray player. This led me to believe the noise has something to do with the CEC / ARC settings and the receiver trying to handshake with a device that isn't connected. So next thing I tried, is disabling all the special HDMI 1.4 stuff like CEC / ARC. No luck...

Tomorrow I will be buying an hdmi cable so I can connect my DELL u2410 monitor and confirm my theory that the t757 is searching for a device to output some kind of signal to. Shame that Dell only supplied me with a displayport cable, otherwise I might have had something conclusive today.

Going to try this since the distributor / NAD didn't notice anything wrong when they tested the device before sending it to me. They did test and resolved the delay issue by updating the firmware, so I know they at least tested the receiver. They very likely connected other devices / a display over HDMI in order to test my reported issues.

Will post my findings tomorrow.


Regardless, I am contacting the dealer again tomorrow and will demand a repair or a refund. The NAD AV receivers may sound well, but the amount of issues I've had, make me wonder about the overall product quality. Right now, the receiver simply does not work as advertised (doesn't feel like music-first).


Edit 1: Contacted the dealer, who in turn contacted the distributor. The NAD technical department will look into the issue on the receiver I returned yesterday.
Edit 2: Tried plugging in my Dell monitor today (it's only an output device though). This didn't do anything to solve the buzzing.
