Thank you for replying. Are you located in Europe? So why NAD insists in version 1.39b and not send 1.40 to my local dealer?

Yes, I live in the Netherlands. Took me some effort in getting my dealer and the local distributor to solve my issue. Only after contacting the Canadian NAD support desk and Lenbrook, I was notified of this new update.

Armed with this new info and the name of a NAD contact, I got my update... Which summarizes the last three months before my post about receiving a fix...

Hello,

Just checking in. It's been a while now since I installed the firmware update. I have not experienced the volume spikes since. Seems like the problem is definitely fixed. I went ahead and connected a Mcintosh MC 452 (450 Watts) to the preamp outputs. The NAD performs pretty good as a pre. I'm pretty amazed.

I am running v1.40 now,and I must thank you Flozem for the knowledge sharing. Buzz noise is gone with version v1,40, it was still there with v1.39b. So... very happy for a start.
I used v1.39b for some time and the volume moods did not happened, let's see how it behaves with v1.40 for a medium/long term.

Whatthead, thank you for your inputs too. Please keep us updated.


I am terribly happy with the NAD sound and vídeo performance. What about the others in here?

I noticed that Crutchfield is now selling a T758 model. The specs look the same as the T757V2 but the back panel is re-arranged quite a bit. It still has 2 MDC card slots and it looks like the same cards (AM100/VM120). I asked NAD about this model but they denied it exists ("can't speak about future products"). That's a bit strange given that it's for sale at Crutchfield at least.
post #217 of 239
I noticed the T758 as well. It's really too bad they didn't allow for more than four HDMI inputs and add another MDC slot. Like you say, it looks like they just re-arranged things --- I wish they would have changed the HDMI input orientation as well so they're not vertical.

So, the T758 is on NAD's site now. I can't really see what's different than the T757V2 though other than the re-arranged connectors on the back:

They both have identical specs. Maybe a good time to get a deal on the T757V2???

Can anyone please answer this simple question? Does the NAD 758 (or 757 - I assume they'd function the same in this regard) allow you to pass through video from one HDMI input while listening to audio from a different HDMI input?

I assume, but am not sure, that one could watch video from an HDMI input and listen to audio from an optical digital input. Is this correct?

I am looking to upgrade from a (now seemingly ancient) Yamaha AV receiver that has served me well over the year but has no HDMI at all. It's definitely time to move on. I'm not really in a position to spend more than what I've seen the 758 listed for, and among AV receivers at or around that price point the NAD is the one that has me most intrigued. Yet I am a bit disappointed that there are only 4 HDMI inputs on these NAD receivers. If I'd like to listen to music from one source while looking at a slideshow from a different source, or while watching a ball game or something from my cable box, I'd need the ability to have video pass through from one HDMI input while listening to audio from a different HDMI input.

Thanks in advance for your help! I really appreciate any info. This is something I've tired to find out around the interwebs and I'm coming up with nothing so far.
post #220 of 239
OK... starting to get worried again with my T757...

Yesterday the volume suddenly droped but I didn't pay to much attention. Than today it suddenly raised to maximum level. I was very happy v1.40, but now...

Anyone still with volume problems/swings with version v1.40 or is there a new upgrade?
post #221 of 239
I'm interested in the T757
But what about 4K (when that time comes... as it will)?
Will the receiver be able to pass the signal, that is 4K passthrough?

No, as far as I can tell.

On the 757, the HDMI video and audio sources are locked together. You can choose optical or coaxial audio with an HDMI video source.

 

So Dark Side Of The Moon SACD with 2001 A Space Odyssey Blu-ray requires some re-wiring :(

don´t think it´s capable at the moment. but I assume that there will be a new VMxxx which will support this. however, I don´t see this happening in the next 2-3 years.
post #224 of 239
Are you running your 757 in bi-amping mode?

I was wondering how much maxpower (main supply) the 757 can handle.
post #225 of 239
Bi-ampig the T757 here... since purchased. Perhaps not the best speakers in town, but I have these since a long time ago and I am very happy. Running a pair of Absolute 2 monitors (not speakers) from Spirit by Soundcraft. True sound and without any colouration.

Any T758 owners out there? Recently purchased one and was hoping to get some discussion going on this unit

I am just waiting for my local supplier to get one. They still have the t757v2 in stock and claim it is just a vendor change, so they are in no hurry to get the new model. I still think something must have been changed as the rear connectors are different. Would be nice to know if you are running into any problems previously discussed on this thread or perhaps new ones. Anyway, congratulations on the purchase and let us know you impressions.

A couple observations after only a couple days with this receiver:

PROS--This is the best sounding receiver i have heard. i am coming from a $500 mid-line Denon and there is no comparison. The sheer amount of power and detail is night and day between the two. I also briefly had a Yamaha Aventage hooked up (it died rather quickly) and it sounded really great, but not as clear as the NAD with music especially.

It is a very simple unit to setup and operate (assuming all the options work correctly.....will get to that in a second). Simple, very simple menus which I like. I don't need a receiver for 100 different zones, streaming music, etc. I use other components for streaming (Oppo 103) so i like the bare bones approach.

It also runs very cool.I have it enclosed in a cabinet and it barely gets even a little warm, so zero chance of overheating.

it also feels very solidly built.

CONS--the Audyssey setup does not work. Everytime that i try to run it, I get a check type beside all speaker types. The speakers are hooked up correctly, and the test sound waves are played through them, but then it says check type and cannot go further. i will setup manually with an SPL meter, but this is a problem.

Another thing--although the 5 preset sound modes is a nice thing. they sometimes have problems switching. Maybe some of this is user error with it being a new unit, but like i mentioned, setup is pretty elementary and I can't imagine that I'm doing anything wrong here. The dynamic range control similar to Dynamic Vol on Audyssey units does not work at all. I have changed the settings and stored them several different times, but when you switch back ot the preset, it is every bit as loud as normal range. Any advice from other owners would be welcomed.

Lastly, i can't seem to get any bass output from the subwoofer when switching to Directv. The sub is on and crossed over at 80 hz, but there is no output with this unit. This is probably user error.

Anyway, there are some kinks that hopefully i can get ironed out, but this unit is very well built and the sound quality makes up for the small problems for me. Just a beautiful sounding unit.

What firmware is your T758 running? If they truly haven´t changed anything the firmware should match the latest in T757, 1.40. If they are completely unrelated, maybe it needs a firmware update to iron those bugs.
post #230 of 239
Not sure on the firmware. i will check that when i get home....
post #231 of 239
I don't think Dynamic Volume and Dynamic EQ will work until you've run the Audyssey setup.

I have a T777 and had the volume issue where it increased and decreased on it's own. I was on firmware v1.38 and NAD sent me the latest which I installed today and it is now v1.41.
post #233 of 239
My volume doesn't increase/decrease on its own, but i can't notice any difference at all with the dynamic volume controls changed from 100% to 25%. I'm not sure how to check which firmware I'm running.....dumb question i know......

If the T757 is like my T753, the Dynamic Range Control only works when Dolby Digital and DTS are being used (and you have to set it up separately for DD and DTS). I know the T757 has audyssey, but not the Dynamic Volume part of it.

Got this instruction from Lenbrook earlier, on how to check which installed firmware version I had:
simultaneously press < SOURCE + SOURCE > (arrows indicating left/right, use the the selector on the receiver).

I also have a 777, and the "old" firmware. Did the upgrade fix any other issues? I wonder as I have some sporadic problems with the handshaking process between the receiver and the ATSC-tuner, the screen turns yellow and I have to switch to tuner off/on. At times the receiver also loses track of the signal which makes for disturbances in the overall sound. Did you get the v1.41 as a link from NAD or from your dealer?

I haven't tried bi-amping before. Is there a major difference in soundquality?

I think the tech bulletin mentioned addressing an HDMI issue but someone had posted that they don't always list all the fixes....I received it as a link and downloaded the files. If you want to send me your email by PM I would be happy to send it to you.

Sounds like the handshake-issue might have got fixed? Yes, if you would send me the files I'd really appreciate it! Thanks a lot! I'll PM my e-mail! smile.gif
