One silly question. I am about to buy a second hand unit, will I be able to use the Dirac License? Or it remains in the PC of the original owner?

Thanks

There are 2 versions of Dirac one corrects over a limited range i.e from 20-500hz and the other applies correction over full range i.e 20-20khz. The limited one is free and comes with the receiver, just download Dirac software from NAD website or from Dirac website . The full range one has to be purchased and cannot be transferred but if your seller agrees to share his Dirac account details you just need to login once in the above downloaded software and it will locked to your PC/Laptop until you have to wipe and install freshly again.
I hope this helps.

Also to add if you ever purchased a Full Dirac for other AVR say Arcam I think you can still use those account credentials for NAD also. The software it not tied to the unit but to your Dirac account.

That helps a lot indeed, thanks! When you say “comes with the receiver” how does it work? Do I create an account and enter the serial number? Is this not creating room for piracy? And yes, I would upgrade to the full version

After my dealer sent me back my NAD saying they couldn’t find anything wrong, they’ve finally agreed to replace my unit with a new one.
Will i be able to use my existing Dirac account (upgrade) with the new unit?

Why when the suggestion to be able to boost heights through a preset DIRAC slot was it said to raise all the levels ABOVE 5k Hz only?? Why not raise all or more of the height speakers range? Is this arbitrary?

Also, I did try that and only raised 4dB all points above 5k Hz...should I raise more dB and lower the range I bump the curve?

hi - two separate points here:
1. Following the natural speaker curve above 5Khz - as has been stated this is a preference.
2. Boosting the heights - just apply for example the 4Db Harman curve (or NAD Room Feel Curve) across the entire frequency spectrum.

So I would do the 5Khz curve following first and then the 4Db boost. But all this is preference - do whatever works for you.

I did ask Dirac how to do this and they responded:
Hello,

I think that your approach is correct and you can evaluate the expected results by looking at the after correction Dirac graphs of those specific channels

Best regards
So this does seem to be the Dirac preferred approach to boost heights - Thanks - George

Nope, as per knowledge NAD shares a list of devices serial no’s with Dirac and the software validates your device’s serial no in that list. Once it finds a match the software is activated and it’s only then you will be able to use it.

So above boosting above 5k is YOUR preference or accepted practice? What I did was do room feel for all groups of speakers and then with the heights I boosted the freq above 5k by 4dB-is this essentially the same as what you recommend?

Would it be better to start boost around 1K? What would be the draw backs with that?

I don't really understand this boosting above a certain frequency. You want the speaker to sound the same, only louder. That means all frequencies raised or lowered equally.

If you only want the speaker to sound brighter, go ahead and boost above 5 kHz. Maybe you have duller speakers and would prefer that. But it's not a rule.

That’s exactly what I was confused about-the other person recommended boosting above 5k...I didn’t understand why.

Would the rest of NAD owners that want to have a DIRAC slot dedicated to the height/ceiling speakers being louder just

A) after rubbing DIRAC select either default flat curve or room feel for all speakers

Then,

B) raise all the points on the correction curve (flat or room feel) by 4-6 dB

Does this sound right for the best way to have a preset with ceiling speakers more pronounced?

4-6 dB might be a bit much, but you'll have to experiment to see how it works with your gear. But otherwise, yes.

Easiest to edit the text file. Dragging with a mouse is fussy (for me).

Ok. Maybe I’ll keep it at just 4 dB but bump the whole freq range with the in ceilings and not just higher then 5k as I did last time (not sure how much sounds I am boosting if it is only above 5k).

Also, what do you mean edit text file? I don’t think I saved the file when I did my room correction-I just did it and saved the 3 slots with different curves....can the slots be edited afterwards if the original file wasn’t saved?

Also, I believe I just dragged the points on the graph up that let me with the mouse 4 dB...didn’t seem like anything was fussy...?

You can open the individual “curve” files within a text editor. There you will see the frequencies with their corresponding dB boost or cut. From there you can manually enter the value rather than trying to land on the correct db by dragging a mouse....

Thanks. I’ll try it from that way from now on.


Is there any way to edit a Dirac slot further after the fact if I didn’t save the project?

That quote of mine was about 12 months ago I think, when a lot of issues with the NAD were being reported here. I haven't followed the thread closely for some time, but I would hope that by now all such issues have been resolved. Current owners will no doubt tell us the up to date position.

Wow you are right, sorry, I did not realize your comment was made so long ago. Thanks for the update anyway, good to see that the issues are gone, especially the “buzz-gate”.

I asked because I’ve always had Yamaha, and never had an issue. Now, I want to try Dirac and the musicality of NAD. For me, this receiver is “strangely” cheap, my Yamaha costed more, and it does not have Dirac, the continuos wattage over 7 channels or the music-focus that the NAD has. Looks like a bargain

I know there are some backdraws, like few HDMI inputs, no OSD, etc. But the quality (=lack of issues) is my main concern

I think it is an excellent unit, and the inclusion of Dirac Live more than makes up for a lack of bells and whistles, most of which usually go unused anyway. Dirac Live will give you a very significant increase in perceived sound quality and is probably the most sophisticated room EQ system currently available, at anything like an affordable price. Combine that with Dolby Atmos and you will be in for a great experience IMO.

Thank you! Has anyone gone from Yamaha to NAD to share the experience?

You have pretty good speakers that don't need correction. But, do you have significant bass issues in your room, or do you have a layout that is not ideal due to spouse or other factors? Dirac would help.

Yes, my speakers are boomy and I don’t like the adjustments on the low frequencies that YPAO makes. If I remove the integrated amp, the boominess is almost gone, but sound quality is worse (Yamaha alone). I want to remove the integrated amp and change the AV with one which goes better with music, and I am curious about the sound signature of NAD (apart from Dirac)

I emigrated from a Yamah RX-V781 to the NAD 578V3. Its a lot more amplifier per speaker, and for medium sized rooms I think the onboard amplification is more than enough. In terms of signature, Dirac will make it so the NAD sounds like whatever you want. More bass, less treble. It can all be configured by you. I recently integrated my stereo and home theater into one, and for that reason I now have a Hegel H160 powering the fronts. But that's really just so the Hegel doesn't gather dust. If you want to use a separate amp for the setup you, should maybe look at the T777V3. Its got 20 more Watts per channel, and a bigger transformer. So its possibly better at divesting power to some onboard amps, when others are not in use.

TL;DR: compared to my Yamaha unit I find that the NAD has better build quality, better amplification, and Much better EQ. Bass response is especially more 'tactile'.

Edit: just saw you have the 2070. Build quality is probably similar then? But I think my unit had the same version of YPAO (YPAO-RSC).

Thanks for the insights. In fact I want to replace my A2070 and the integrated by the NAD, knowing that I will have less headroom but more EQ possibilities. My doubt is if the NAD is better than the A2070, apart from Dirac

Yamaha, in my experience, is the most reliable brand in the market. The T758 has multiple issues that keep coming to many users, mainly: ARC, Bluetooth, Atmos hiss, 4K pass through. And also you must take into consideration (if you haven´t) the limited number of HDMI inputs and probable need for external amp.


Sound is incredible, yes. But not that far from a high end Yamaha. I would switch to the A3080, but if you´re lucky, you might get a flawless T758 too, like many on this forum have. It´s really a hit or miss thing. Good luck!

Wow, now I don’t want to risk switching to NAD... thanks
