Bit Disappointed in NAD


I have a C375BEE integrated that I bought awhile back that I like quite a bit. Built a new house, so my system was in boxes for awhile. Finally finished the house, so I unpacked my system and bought the MDC DAC 2.0 card from Crutchfield to add to my amp. I specifically bought this DAC so I could stream from iTunes via the USB input on the DAC. Installed the DAC, and right away noticed a significant buzz ONLY on the USB input (buzz rises/falls in step w/ volume). Tried the phono and optical inputs on the DAC, and they are fine, no buzz.

Contacted NAD, and was told to bring the amp and DAC to one of their authorized repair centers. Did so, and was charged $65 for a diagnostic fee so they could tell me:

  • 1) Yes, the USB input buzzes
  • 2) No, the unit is not repairable
  • 3) No, there are no more, since the DAC has now been discontinued
  • 4) The best they could do is send me a used DAC 1.0, which only supports 96kHz sampling instead of 192kHz on the 2.0

Now realistically, I doubt I'll be able to hear the difference between 96 and 192kHz. But I'm disappointed that I bought a product from what I thought was a reputable company, and even though they agree it's defective and is still under warranty, the best they can do is substitute an older, inferior product. I'm also really surprised that they don't even attempt to repair these. Personally, I find that these days we live in a bit of a "throw-away" society, and would have thought an electronics company with a reputation like NAD's would have been the exception to that.

It's only a $250 part, and maybe I'm just frustrated because I haven't had any music in over a month now, but I felt like venting a bit.

If it's discontinued is there a new model Dac coming out? If so tell them you want to wait for that. Also it seems odd they have stock of the previous Dac which I assume was also discontinued and not the more current one.
   Yes, you should not have been charged the diagnostic fee with the warranty still in force. I have the same NAD amp as you. The 375 is capable of accepting two add on modules...phono and DAC. Since most of my listening is vinyl I opted for the phono module. The sound was OK but I was curious if the sound would improve with an outboard phono preamp.

   I purchased a phono pre and the improvement was VERY noticeable so now I use that and let the NAD module just sit. Don't underestimate your NAD amp. It is very capable of good performance. Service under warranty is an issue to be resolved with the original dealer or NAD itself. I would fight for the $65 refund. Your buzzing problem could very well be caused by things suggested by others
.
Fight for your $65, plus see if you can get a refund from Crutchfield.  $250 will buy a very decent outboard DAC (Schiit Modi Multibit or SMSL SU-8, for example)
Odd.

Sorry you have to deal with that.

Don't understand why Crutchfield wont just give you the money back? They have a 60 day money back guarantee? And its still listed as current on Nads website.  https://nadelectronics.com/product/mdc-dac-2-0/   Solen still lists it as current. Something seems "off" with Crutchfield as well as a diagnostic fee. 

Good luck.

there was a time when I considered the NAD Master series until I read about the various problems compared to the older NAD products. Quality Control took a hit.

Happy Listening!
