Most BD players now do on board decoding of Dolby TrueHD. inc. the PS3, which is rumored to eventually get an update to do onboard decoding of DTS-MA. None do on board decoding of DTS-MA except the new, as yet unavailable, Denons. (The new Pan. outputs bitstream for both, and has no on board decoding.)

Is there a [noticeable] difference in sound-quality between the T773 and the T775?

If there is, my ears can't hear it. The two units sound identical to me.

I'll be stuck with playing CD's, SACD, DVD-A, and standard-def DVD-Movies (up-scaled to 1080p)-- until a new BD player is released with on-board decoding of DolbyTrue-HD and DTS-HD MasterAudio.

It's the damn DTS-MA that's screwing everyone up. I loved my Panny BD-10 - 7 channel analog outs and decoded everything except DTS-MA. Now the BD-30 comes out at 1/2 the price but doesn't decode anything - but does send it bitstream unaltered over HDMI. So it seems the new generation high-def players keep going one step forward and two back.

Anyone have any experience comparing NAD to Marantz. I am waiting for the NAD 785 to arrive, but the Marantz SR8002 keeps tugging at me as well. I have Monitor Audio GS60's for my front speakers and GS10's for surround, GSLCR for center and a velodyne sub. I know this is a NAD thread but any thoughts? Thank you.

Just curious if anyone has successfully passed a 1080P source through the T775. I have not been able to do so. Tech support @ NAD thinks the problem is HDMI cables not being 1.3a certified. I have ordered new ones, but I have my doubts this will solve the problem since bypassing the T775 and going from BD player to TV works fine with my existing cables.

Any feed back would be helpful.

Not sure if this is related, but further to my problem with the T585 not working with the 775 (via HDMI) .. aparently none of the NAD HDMI players work with the T775 (and I suspect the T765 & 785 as well). This has been confirmed for both the T585 and the M55 players. The problem was confirmed by NAD technicians on Friday afternoon to be with the players and not the receivers (thankfully). There is now a firmware update available for the players. My dealer will be testing this as soons as the DVD arrives later this week.

I am interested in your impression of the sound of the 775. I have Martin Logan speakers (Aeon i, Cinema and Frescos) and have been considering this unit. My dealer has a 765 in stock but not the 775, and does not sell ML. I have never owned NAD before. Everyone keeps saying in other threads it is a "warm" sounding receiver. I take that to mean it is rolled off or "slow" sounding in the treble, which is not for me. What is your take on the sound quality of this receiver?

Yes the problem is likely the cable, especially if you've had it for awhile. To pass 1080p you need an HDMI 1.3 Category 2 compliant cable (which can handle approx 1.5Gbps); older cables for 720p/1080i only required 742.5 Mbps, so there you are. Distance can also be a factor, but less likely if you stick to the mentioned cable spec. Recommend checking with Blue Jeans Cable (an AVS sponsor), had very good luck with them.

It would help if people provided the refresh rate they are having 1080p problems with. There's a big difference in the bandwidth required for 1080p/24 and 1080p/60.

It may be an NAD problem. 1080p/60 is really pushing the bandwidth. There aren't enough people reporting in yet to know for sure.

I doubt it's putting out 1080p60. More like 1080p30 if anything. That's not pushing the limits of HDMI.

But what HDMI products handle 1080p60? 1080p usually means 1080p30, or at least, that's about all it has to mean. Why would you move it to 1080p60? That's a waste of bandwidth. If that's the case, I assume there's a switch for 1080p30 and that should be used.

The wait (10 months) is now almost over, after selling my (fantastic) Nad T163 and Power amps.


Bring it on



Ken

Mine is on its way as well. I hope I will have it hooked up to my Monitor Audio GS60s by the end of next week and will report back.

If you scale 720p/60 up to 1080p, it needs to stay at 60Hz or you will lose information. The Toshiba HDDVD players do this. Any component that claims to do 1080p needs to be able to handle 1080p/60 as well as 1080p/24 or it isn't ready for prime time.

I have same problem. But after warming up for 20 minutes my 775 handles 1080p from BD player, sort of. I still get a second or two of snow once in a while. Those first 20 minutes I have to set resolution on BD player to 1080i. After that, I change resolution again to 1080p and get a wonderful signal from then on. So that eliminates cables as the problem. (They're 1.3a certified, anyways.) Dealer wanted me to try a hundred dollar cable from them to see if that helped, but I don't want the damn thing if it requires hundred dollar cables to function.


I'm returning mine to dealer for exchange, but I know there's no guarantee the new one will be any better. I contacted NAD over a week with the problem but they haven't responded. I'm guessing they're having a huge issue with the HDMI boards inside.

I hope I dont find these HDMI problems in the 785. I wont be able to test it next week when mine comes in because I dont have any 1080p equipment, I have a pioneer elite plasma that only goes up to 768. Sounds like to me this is a 1080p problem?

Same as,


My Projector (Sanyo Z3) can only display up to 1080i maximum.

And what products are doing 720p60? There would be no loss of data. 720p is 720p30. 1080p is 1080p30 or 1080p24. Nothing is recorded in 720p60 or 1080p60, nothing is stored or transmitted in it. It would be senseless to build a product that converts to it and even more senseless to activate that feature. There is nothing there to lose. 1080 is 48 or 60 half frames. 1080p is 24 or 30 full frames. 1080p60 is a dream, for sure, but still nothing more than a dream. The only reason for 1080i is that most CRTs weren't fast enough to do a full frame, so they did it in half frames. If we could go back, it would be senseless to have 1080i60, everything should just be 1080p30. 1080p is not twice the data, it is simply the same data in fewer frames - "pre-deinterlaced" if you will.

No, a lot of displays have 1080p60 as their native display mode, so video processors output that format. Usually 1080p60 is just a result of deinterlacing 1080i into two full progressive frames using either line interpolation from the original field, or temporal interpolation from previous fields, or a combination of those two methods.


And of course all HDMI transmitters and receivers from HDMi 1.0 should be able to handle 1080p60 if they meet spec.
