Don't give up hope. Keep reading and trying things because there's got to be some little thing overlooked somewhere. Most people have not had any issues they couldn't overcome with a little perseverance, I know I haven't. I think the best connection seems to be Ethernet, though I don't use it.

Good news on the M10 for Dirac Live, but also for all the owners of T758v3, T777v3, and M17 with the upcoming release of BluOS 3.4, and it will be demonstrated at AXPONA.

It's ridiculous that we have to make that compromise. Can they fix this with a firmware update?

I'm also having all sorts of problems with Dirac Live. I have the supplied calibration microphone connected to my laptop (as it doesn't reach all the way to the receiver in the gear closet) and the microphone isn't picking up the calibration sweeps properly. It's weird because it works fine when setting the volume for the Dirac calibration run, but once the sweeps start it's not working properly and I can't get a calibration run to complete without errors.

I have a calibrated Umik-1 on the way from Cross Spectrum so I'll see if I can get it to work either plugged into the laptop or the NAD itself.

I can say that my experience with Dirac and miniDSP was much more successful, and the Room Perfect calibration of my Lyngdorf TDAI-3400 was a breeze with zero issues. Looking forward to getting Dirac Live up and running on this thing.

I suppose the more complaints/reports NAD receive, the more likely they are to fix it

Yep. I'll be back at it again this weekend. I've tried the supplied mic from the 758 and from my Mac. Need to find an ethernet to USB adapter to bypass wifi...Hoping for some good reviews at AXPONA.

I stopped updating my older yamaha rx-v781, which had the ability to switch between dolby surround, dts:x, or its own 3d upmixer on any source.

Forgot to reply to this, you've got it backwards. Dolby don't want people applying Neural:X to Dolby signals, I'm talking about the other way around, which I don't believe Dolby have a problem with, it's just not written in their spec so NAD haven't coded it (but every other AVR manufacturer have done)

I received my replacement 758 and have everything set back up - no hiss, no weird sounds. BluOs is much faster with this unit. The iPhone remote syncs quicker, and so does Markus' app remote. It took 3 times for the filter set to load in to the AVR after Dirac though. It had me worried that I was going to have to start over.

I'll be Axpona tomorrow so I'll be sure and check out the updated BluOs

Please clarify:

Ran Dirac from the desktop?
Mic hooked up to the 758?

Thx.

Yeah, it's a tough one, isn't it! I ended up disabling my web browser security which helped get me a connection (I use AVG). Maybe another thing to try. So if I can just get it to do some filters, I can see where the Dirac correction can be great. Still working on it though ( I tried a few times last night, but to no avail). Now I will admit, I am not in IT (not even close). But the results look promising!

Is there somewhere to email Dirac? I'm not sure if mine is a NAD or a Dirac issue right now (off to do more searching...)


Good luck and keep us posted!

yes, i connected the supplied mic using the usb connection directly to the T758v3 and not connected to the computer.
my desktop is located in another room has a wired connection to my network.
that kinda worked out well since nothing else was in the listening area when the calibration was going on.

Yeah, but when I read the article I figured it had to go both ways. Even if Dolby is the one pressuring manufacturers, I don't think it would make sense for DTS to not also implement a restriction. If, in the future Dolby is universally compatible, but other competitors are not. Then Dolby gains a significant advantage, because now the dolby suite can decode all other sources, while competitors cannot?

I was able to get Dirac working properly. I'm not exactly sure what was causing the issue, but I uninstalled the original version of Dirac Live that I had used in the past with my miniDSP DDRC-22D and I also deleted the mic calibration file for the included NAD mic before trying again.

I then downloaded the mic calibration file again, and loaded it back into Dirac Live 2.2.0 and ran the software from my laptop connected to the wireless network. The included mic was plugged into the laptop. Dirac found my NAD 758v3 with no issues and this time the sweeps ran with no issues. I performed 9 measurements and created filters from there.

For now I'm just using the default filters (which do sound slightly bass-shy to my ears) but I'll tweak the filters a little more later on. I haven't purchased the full version of Dirac yet, so the 6dB bass boost Harman target curves don't really work properly when Dirac isn't correcting the entire frequency spectrum.

With Dirac now running everything is sounding a little more precise and slightly more locked into focus.

I strongly encourage investing in the full version, and if you have a calibrated UMike-1 with that miniDSP unit, use that.

Guys,

My room renovation is getting done, just put fresh speaker wire for the surrounds & atmos, now i need to buy some banana plugs. I m confused with BFA Z & normal banana plugs.
will these BFA banana plugs fit our Nad t758 v3? these are the ones-

https://www.amazon.com/Audioquest-Su...na%2Caps%2C371

anyone have these BFA plugs plugged in their T758?


Thanks.

They should be, but unfortunately they are not. They do all start out at a little over 4mm diameter to fit the 4mm receptacle in amps, receivers, and speakers. The maker's choice of copper alloy, the amount of elasticity (spring) it has and the design all matter for how long they may last and how good of a connection they continue to make.

I choose to use locking banana plugs from Blue Jeans Cable. Rock solid connection and I control the tension. I started with Monoprice connectors, they didn't work very good.

Was confused that BFA Banana plugs only work in BFA connectors.
I guess its the normal 4mm banana plugs that don't fit the the BFA connectors right?

I used the NAD supplied mic to do the original calibration of my T758v3. I really like the results so far but realized i have a UMIK-1 that i could have used.
so i'm thinking of rerunning the calibration with the UMIK-1 plugged into the T758v3, when the wifes out. do i use the calibration file from miniDSP for this ?

thanks

Today I loaded firmware and ran Dirac 2.0 for the first time. The 2.2 version seems relatively painless to use, but the Harman curves that I obtained at some point for 4, 6, 8 and 10 db do not appear to exhibit a rolloff from 1K to 20k. Is there a way to change the scaling on the new interface so I can zoom and see what the vertical scale is. My laptop Win10 pc never recognized the UMIK-1 in Dirac and I ended up plugging it into the receiver and running Dirac from my office iMac through the network. Not convenient for changing mic placement at all, but the 27" screen is far easier to build filters on. I still need to enter a network address to access the NAD from the iMac however. Has anyone sucessfully loaded the NAD Roomfeel target curve from 1.2? I'm sure its hidden away in some system folder on the mac.

I'd like to shout out Lenbrook for working with me on a solution to address my defective unit under warranty. Customer support was effective (eventually) in solving the problem. My unit is now running properly.

yes and no. I wouldn't spend the $$ on the audio quest. Find a banana with two locking screws on eBay or amazon. You can use a center punch to expand the diameter to ensure a tight connection.

I then downloaded the mic calibration file again, and loaded it back into Dirac Live 2.2.0 and ran the software from my laptop connected to the wireless network. The included mic was plugged into the laptop. Dirac found my NAD 758v3 with no issues and this time the sweeps ran with no issues. I performed 9 measurements and created filters from there.

For now I'm just using the default filters (which do sound slightly bass-shy to my ears) but I'll tweak the filters a little more later on. I haven't purchased the full version of Dirac yet, so the 6dB bass boost Harman target curves don't really work properly when Dirac isn't correcting the entire frequency spectrum.

With Dirac now running everything is sounding a little more precise and slightly more locked into focus.
Glad to hear it finally worked for you. I don't think there's a user on here that was able to breeze through setup without a single difficulty, but I will say, after I finally got Dirac to do what its supposed to it really is impressive (I set different curves based on my wife's habitually rearranging the furniture in my living room...hey, as long as she doesn't change me out I'm OK).

I used to dabble in low-mid level 2 channel and tried many integrated receivers in the $1-3K level and I have to say that very few of them sounded better, more balanced, more authoritative that this NAD and none had anywhere near the bells/whistles (or any room correction) so, I gave up the component switching when I bought the NAD...it just does so many things right and I'm currently running it 2 channel full range with Monitor Audio Silver 300's in a 1000 sq/ft living room and at half volume my wife yells for me to turn it down! (when she's gone I use a fuller bass curve, when she's here I dial it back flatter with bass trimmed).

Anyway, just another satisfied customer...thanks to all on here who've helped troubleshoot along the way, especially Markus767 and RichardSim7, NAD truly does owe you a debt of gratitude because this receiver is NOT plug and play usually. Anyway, back to enjoying my receiver....oh, right after I download my BluOS update with DTS:X...darn, now I'm going to have to buy some more speakers/amp and get this thing running full 9 channel DTS:X surround.(interestingly, the NAD website already has DTS:X logo now listed on the 758 V3 page https://nadelectronics.com/product/t...ound-receiver/)

Happy listening all!

I was able to obtain a copy of the RoomFell curve from NAD's website. I wish I could remember where the link is located but I'd be more than happy to share it with you if you'd like bud.
