Current owners , any further insights ? ... Tell me your (NAD) love stories. ;D
Some have mentioned the lack of comments (or reviews, I guess) regarding the T747. Since I just received mine a couple of weeks ago, I will offer a few. Please keep in mind I haven't played with it a lot and I'm in the middle of experimenting with a bunch of homemade sound absorption panels and a new media player so everything's in flux right now.
Current Environment: I listen to a lot of music (FLAC) and have around 800 DVD & Bluray. Equipment hooked to the NAD includes a Sony 60 SXRD, Panasonic BR, Dish Network decoder, and a couple of networked media players, and some vinyl equipment. The main speakers include Polk SDA 1C (1988), Polk center, NHT surrounds, and a Boston sub. My previous receiver was a Harmon Kardon although my Outlaw processor was hooked up when the NAD arrived. Both the HK and the Outlaw were used with a Carver AV-705THX 5-channel amp which puts out around 160 X 5 real watts into my 5-6ohm setup.
I started looking at the NAD receivers in an effort to start simplifying and still maintain the sound I like. Over the last 25 years the affordable processors I've owned that come closest were from NAD, Rotel, Outlaw, and HK. I respect the fact that everyone has different needs (and opinions) but for me it has never been about the IPod docks, video up-conversion, and 25 DSP modes. Getting lost in the music and the movies is the goal.
The T747 is a very well-built piece of equipment. I've always appreciated the clean, simple look of NAD equipment. What's not to like about heavy gauge steel / aluminum, gold plated connections, thoughtful layout, and simple controls. The HDMI connectors are extremely secure (HK's are not). I read one review where the binding post spacing was criticized but I'm using banana plugs with 12-gauge and find no issues at all with them. Perhaps with a bare wire connection a little more care would be required. All of the front controls have a nice, solid feel. The display could be a little larger but it's clearly visible from 12-13 feet.
I have not run the Audyssey configuration yet (sorry) but the initial manual setup was very easy. As others have commented, the GUI isn't the fanciest in the world but it does get the job done. I'll get a few minor complaints out of the way by saying the remote is a so-so thing, especially working with the GUI setup. The range is not great and on mine the back button refused to function dependably unless I moved to within 4-5 feet. The issue is with the remote - not the receiver. Switching to my universal remote solved all the issues. On the plus side, the remote is very well laid out and being able to cycle through the surround modes with a single button is absolutely great.
Video functionality for me has been good so far. I have not experienced any HDMI handshake issues or audio / video dropouts. Switching sources is very fast compared to some receivers I played with lately. I am not using any analog sources (all HDMI) except for occasional turntable use so your environment may be different. As I mentioned in an earlier post, I am getting 1080p out with a Normal setting even with 1080i input so some level of processing is going on. Whatever it is (if any), it must be minimal. My recent experiences with a Pioneer, Onyko, and an HK were similar so maybe there isn't a true video bypass out there. I will say that in my opinion the output quality to my Sony is outstanding with all input sources. A temporary volume level display GUI would be nice but that might entail more video processing so I won't complain.
I suppose power is the big question in a lot of people's mind. I will say that Polk SDA from the 1980's sound better with a lot of power, and they typically measure out around 5-6ohms so they can be a load so to speak. One of my questions was whether a 60 watt receiver (even a NAD) could drive them comfortably. I'm happy to report that the T747 has to be delivering the 100+ watts X 5 (8ohm) measured by Home Theater magazine. Not having expensive test equipment I can't certify the actual power out to my speakers but I can compare it by ear to my Carver amp (certified 125 into 8ohm) and the NAD doesn't lose by much. At this point I'm not sure whether I will keep the Carver and use the NAD as a processor (more testing needed) but it is nice to know I have options. For those worried about heat, I run mine on the top rack shelf so it is open on all sides however the top of the box is barely warm after several hours of use so I don't think heat is an issue.
The bottom line for me is the sound quality and that is a very personal thing. Your preferences may be entirely different than mine so please keep that in mind. I prefer a more laid back sound (used to be called the UK/English sound back in the day). I suppose mellow or effortless are other applicable terms. That isn't to say I prefer quiet or low volume. Maintaining laid back at 100+ db is a trick few receivers can pull off. I have been very happy with my Harmon Kardon overall and I've recently played around with a Pioneer (a little bright, limited dynamics), Onyko (harsh to my ears), and a Marantz (actually pretty nice sounding). To my ears the 747 is in a different league. I don't want to go overboard with glowing superlatives (tough to describe sound quality) but this receiver is very, very good at what it does. I'm not sure this will make sense but with the volume at background level the sound is detailed, warm (overused audio term), and involving. As you turn the volume up, those qualities do not change. Tough to describe so I guess it's one of those you have to be there things.
If you're more of a movie fan, I doubt you will be disappointed there either. I'm only doing 5.1 but the decoding and channel separation is excellent, and immediately noticeable. Dialog is noticeably clearer than with the HK and the surround channels are more active. Eventually I will get around to running Audyssey but I have become pretty proficient at manual setup with a DB meter so it's more of a curiosity thing.
I don't change surround modes very often but occasionally it comes in handy (5-channel stereo for parties, PLII Music for TV concerts, etc.). The NAD is pretty good at the default level but being able to cycle through the surround modes without resorting to the GUI is a real plus. It's the same with the preset functionality. It's nice to be able to include/exclude the sub-woofer. With several of the receivers I auditioned, it seemed like I was constantly going into the menu system to change a simple sound parameter.
So is it perfect? Well I wouldn't go that far. Would I like a better GUI, Ethernet firmware upgrades, streaming and Internet radio, pure video pass-thru, a better remote, more power, etc.? You bet, and you can get some of those things from a number of mid-range receivers - and probably save some money. For me at least, it pretty much started with sound quality per dollar spent and then moved to the less important features (for me, anyway).
In my decision-making process, I quickly eliminated almost everything but Pioneer Elite, Marantz, Rotel, and the NAD line. At one time or another I have owned all of them so that helped.
Although I may have more comments as I get farther along with the 747, for now I'm very happy with the decision.
