  2. I downloaded the latest bluos firmware C390_usb_stick_3.2.10.zip for c390dd from nad and it now includes three files rather than two: c390.img c390v2.img c390v3.img That c390v3.img is new. So I expect if they have not already, Nad will soon announce a new bluos v3 MDC card that supports apple airplay 2 - like the new blusound node 2i does. So if you are thinking of buying a blueos MDC card you might want to hold off for a bit.
  3. You using linux? Nice. That release notes link is wrong, found the right one on the Bluos module page. No install instructions though: https://nadelectronics.com/wp-content/uploads/2010/02/BluOS_ReleaseNotes_3.0_Public.pdf I would be surprised if you don't already have a recent Bluos firmware on your MDC card if not the latest. While you have the option to update the Bluos MDC module with one of those .img files, the Bluos MDC module can also be updated over the Internet which is easier. The BluOS Controller application or app will bug you every time you start it if there is a new firmware out that you have not installed (if the controller app is new enough). It gives you the option to upgrade the Bluos firmware via the app, or delay the update. Oh - and if you are still using the old NAD branded Bluos controller app - it is no longer being updated - we are meant to use the Bluesound Bluos Controller app now. See here: https://www.bluesound.com/downloads/ One way to check which Bluos firmware you are on: - select the Bluos input on your C390DD - press right arrow on the front of the C390DD to bring up the Bluos menu - press right arrow on the front of the C390DD to select "Bluos Info" - it will show you the Bluos version, eg Bluos v2.14.7 (that is what I am on - I stopped updating) I would expect anything from v2.2.5 or newer would support MQA If you don't have access to a recent BluOS Controller application or app, then you can upgrade from the C390DD. Enable the "BluOS SETUP MENU" using the instructions starting on page 9 of the C390DD user manual: https://nadelectronics.com/wp-content/uploads/2016/09/C390DD-Direct-Digital-Integrated-Amplifier-English-Manual.pdf Then you can continue to follow the instructions to upgrade either over the Internet or using a USB thumb drive. If you choose to use the .img files, some extra notes: - since you have the older card you need c390.img - you need a USB thumb drive formatted as fat32 I think, with nothing else on it. - copy the c390.img to it. Nothing else should be on there - eject and remove it safely from your computer - follow the rest of the Bluos upgrade instructions in the C390DD user manual Note however that if you had to do all this because you can't use a recent BluOS Controller application or app, then if you upgrade Bluos firmware then you might not be able to control it with an old controller. You might be able to - not really sure. One other thing that might help later on: "The MQA logo shown in the BluOS app indicates that the unit is decoding and playing an MQA stream or file" from https://nadelectronics.com/product/mdc-bluos-2/ Anthony
  4. I don't have an answer on behalf of Tommo21 so that is still for him to answer (though I thought his comment was pretty clear), however a separate comment. MQA is listed as supported on both Bluos MDC modules. Have you heard or read something that specifically says the old Bluos MDC card does not support MQA? Perhaps you just need to ensure you have a recent Bluos firmware for your card and give it a try? A search for MQA at NAD lists both cards "MDC Bluos 2" and "MDC Bluos": https://nadelectronics.com/?s=mqa Both products list MQA capability in their product pages: https://nadelectronics.com/product/mdc-bluos-2/ https://nadelectronics.com/product/dd-bluos/ MQA has apparently been available on "C 390DD (equipped with the DD BluOS MDC module)" since "BluOS firmware, version 2.2.5" from around September 2016: https://blog.nadelectronics.com/mqa-now-available-on-nad-2f8d4e3557ef I have no interest in MQA but hope it works for you on your existing card. Good luck.

  11. Very interesting post over at diyaudio.com: NAD C390DD (C 390DD) does not power on failure with fix http://www.diyaudio.com/forums/class-d/326613-nad-c390dd-390dd-power-failure-fix.html Ergo wrote: "I was repairing a NAD C390DD for my friend and tough I'll post the solution here too as this type of problem is likely to happen on other units and I did not find it documented in web prior to this. Symptoms before fix A) When powering on from back panel power button the orange 'sleep LED' comes on B ) After push of the on/standby button on front panel 1 click of a relay can be heard and the orange led turns blue ... display will so no sign of life. Not other relay clicks follow. The unit does not switch on. Problem appeared to be in secondary PSU which supplies the +5V and after switch on the +12.5V. The +12.5V power line showed only +4.5V after the step B. So clearly something wrong. Anyhow, longish troubleshooting later it turned out to be a fault in following capacitors." Ergo replaced capacitors C204 C205 C210 C211 (capacitor numbers marked on the board and in the service manual) from PSU-B to fix the issue. So great news that this issue can be fixed just by replacing capacitors, and Ergo did all the troubleshooting to find out which ones. The green capacitor that is swollen on my PSU-B is a different capacitor C212 so that is one extra one I would need to get replaced if I ever get this "power on" issue. I expect it is only a matter of time. Of course the other option is getting the distributor to replace the faulty PSU-B and maybe PSU-A assemblies. I think someone in this thread said they are $500 each in Australia plus labour out of warranty, so could get quite expensive going down that route. Might be fine for some people. Might be much cheaper in other countries. Anthony
  12. Hi @digitmaster I didn't follow your instructions exactly but I was able to replicate the issues. Seems like two bugs here maybe. One is auto standby not working for high sample rate setting on single ended input at fixed level, and the other is the weird instant auto standby when you select another source after single ended input should have gone to auto standby earlier. These are as you describe and they are related bugs but I will talk about them separately. The difference in my testing is that I have no sources plugged into my MDC DD AP-1 module at all - and I get the same issues. So should be very easy for NAD to replicate. I am using older 2.90 firmware. Have not upgraded to 2.92 yet. Are you using the latest firmware? For the first bug: Since you mentioned it happens with 192kHz and 96kHz (and then maybe not 48kHz), I thought maybe your source, even when turned off might be emitting high frequency noise that is above 24kHz (perhaps due to picking up noise from other equipment or some weird ground loop) so only the higher sample rates would see it and would consider it not silent enough to auto standby. While I was testing at 192kHz with no source device connected, I measured the AC voltage on the speaker terminals to try to determine see if there was noise I could not hear. It registered 0.000V AC so I would think that means no significant noise? I still had the same issues as you - no auto standby and instant standby when changing input. Some other tests - trying to determine if lower volume would help: I tested with 48kHz and fixed trim and auto standby did work. I tested with 192kHz and trim set to zero and volume set to -20.0dB and auto standby did work. I tested with 192kHz and trim set to zero and volume set to 0.0dB and auto standby did not work. After 30 minutes of silence, pressing source scan up button on remote changed source to digital coaxial 1, then immediately went into standby. I tested with 192kHz and trim set to zero and volume set to -3.0dB and auto standby did not work. After 30 minutes of silence, pressing source scan up button on remote changed source to digital coaxial 1, then immediately went into standby. I tested with 192kHz and trim set to -3.0dB and volume set to 0.0dB and auto standby did not work. After 30 minutes of silence, pressing source scan up button on remote changed source to digital coaxial 1, then immediately went into standby. I tested with 192kHz and trim set to zero and volume set to -6.0dB and auto standby did not work. After 30 minutes of silence, pressing source scan up button on remote changed source to digital coaxial 1, then immediately went into standby. I tested with 192kHz and trim set to zero and volume set to -10.0dB and auto standby did not work. After 30 minutes of silence, pressing source scan up button on remote changed source to digital coaxial 1, did not go into standby. With these tests I was trying to determine if some volume a little less than 0dB would stop the issue, so that we could just ask NAD to set the fixed setting to a lower volume, or have it adjustable. But it seems you have to set the volume a lot lower eg -20dB to stop all the bugs so that is too low. For the second bug: I have another possible workaround, but it might not be suitable for you. If I have single ended fixed with auto standby enabled 192kHz, and after 30 minutes of silence instead of using the source scan button on remote to change input, if I press 6 on the remote for "Computer" input (computer USB interface), it changes input and does not go into standby. Perhaps you could try this with one of the inputs you have enabled? A problem with this workaround is it requires you (and perhaps your family) to remember to do this if it has been idle. It is probably not the first thing people think of when they just want to use the hifi system. note: My Computer input always has lock so it is never idle. My digital coaxial 1 input did not have lock at all during these tests, so it may be related to why switching to digital coaxial 1 after 30 minutes triggered the second bug as I was stitching to an idle input? I have not tested switching to an active digital coaxial 1 with sample rate lock. If NAD is not going to fix these issues, I would think the most preferable workaround, for how I think you wish to use the system, is using the 48kHz sample rate for single ended input so you avoid the bugs. But that is just me - you might have different preferences. Anthony
  13. Can you describe the bug? I have auto-standby disabled but I could try and replicate the issue.
  14. C390DD is made in China. Did some more research. The green capacitor that seems to be in the worst condition on PSU-B board is a Lelon capacitor which is considered to be a relatively dodgy brand for capacitors. has marking on it like this: lelon RGA105C A101(M) 47 µF, 400 V If I have identified the correct model it is probably this: http://www.lelon.com.tw/en/product_content.php?id=415 Fairly low ripple current rating and rated 2000 hours at 105C. I can get higher rated Panasonic and Rubycon replacements for that one from element14 that are rated at 10000 hours at 105C and higher ripple current rating. They are considered good brands. The big brown capacitors on the PSU-A board and the DDFA board are marked IC which is ILLINOIS CAPACITOR brand which I believe are considered good quality. Anthony
