I could start off with something like, "I'm sure glad that NAD finally got their act together, and got rid of those crappy, inferior
amplifiers they were using before, but that would seem argumentative.
Not to be argumentative or anything here, but I find it hard to get my head around a theory that someone would offer that a previous model of a flagship component would have "Inferior amplification technology", and "Inferior bass management capability" only because of a (assumed) upgrade on both the amplification stages and a upgraded (assumed) version of Dirac room correction software. This amplifier technology has been perfected upon for years, and still
demands a premium price tag. The Marantz, Denon, Onkyo, etc, brands don't seem to be towering over the NAD series of AVR's, so I'll take that with a grain of salt.
Dirac is over rated in my view, perhaps due to the lack of room correction needed in my particular instance, but I seem to be the minority here. I need a hands on instance where I can take a room with horrible acoustics, and press a button, to have it miraculously be transformed into a magnanimous listening experience. I've heard great things about the software, but that was the old, "Inferior" version. Of course I'm being facetious, and just joking with you HTNUT1975 here.
There are a number of posters on the T758 v3 forum who are claiming that their sole reason to purchase that particular unit, is because it offers a version of Dirac, without breaking the bank. If they are updating/upgrading it in the T778, then that's all the better for all persons who are interested.
I don't know if this new amplifier technology is what it's cracked up top be or not, but I do agree that it sounds like a step in the right direction. I have seen the reviews on the Masters series that employ this amplifier technology, and while it may be an improvement, it's certainly not worthy of discounting the superb technology deployed in previous NAD award winning AVR's. I would think that the R&D has been paid for somewhat by the number of components that have already been put out by NAD in their Master series, so there's that. I would love to get to audition these components for myself. I need to get off my butt and take a trip to Gramophone, or some other dealer I guess. I still see some owners of the NAD "Silver Series" claiming that that era was the pinnacle of NAD's audio component expertise. I've never auditioned any of those components, but would love to someday.
I guess the "Issue" of the LED vs OLED technology has been solved. I guess the LED choice was a better one than OLED, but I'm still investigating that to see if NAD made the better choice in that instance.
