Two DSP Hardware Failures

Guest from Atlanta, GA on 6/19/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

My unit (an NAD T187) came with a VM 300 card from the dealer and it failed (DSP Failure) within three months of use. I had it replaced under warranty for free. Three months later, the left channel started making shorting noises and four days later no sound output. I noticed a firmware upgrade and performed that through my ethernet connection, it failed at the DSP step. It's back in the shop being fixed under warranty ... The NAD T187 and the sound quality produced by the VM 300 card is exceptional. The build quality / reliability though has me very concerned ....

Pros: Awesome sound and seamless 4k passthrough; I don't use the BlueOS functionality, I'd prefer plain Bluetooth, frankly.

Cons: HDMI ARC handshakes with my Samsung TV do NOT work. No bluetooth functionality. The Digital Signal Processor (DSP) on the VM 300 keeps failing under warranty.

Expensive. I'm not sure if there's any glitches at this point. I haven't had it very long. I got it to use with the BluOS and not for 4K video.

I feel this item deserves a 1 star due to lack of documentation. The instructions for the physical install of the VM300 module are good, but the firmware upgrade install instructions and all the firmware are not! I cannot even locate the M15HD on the NAD website. I will update this review if I am able to get all documentation and firmware, but until then it will get 1 star and maybe even returned. *I know they suggest having it professionally installed, not very feasible for me. At this price it should come complete with all that is needed to complete the install!!

This upgrade actually works!

Just completed the VM300 upgrade on my M15HD. I didn't have any issues and the whole process went quite smoothly. I used the firmware link from NAD's website here: For the OSD software, I was all ready with a USB stick, but the firmware loader gave me the option to use the Ethernet connection on the VM300 to get it, so I went that way and all was well. I honestly expected issues with this upgrade, but it all went just fine. I'm happy the M15HD has MDC modules... pretty slick way to keep your processor current!

Pros: Works without issue, as advertised

Cons: Pricey!

Mixed bag

Guest from Ann Arbor, MI on 4/14/2017

Verified employee purchase (What's this?)

The VM300 is definitely a mixed bag. On the one hand it does the main thing it's advertised to do: add 4K HDMI2.0a functionality to some NAD AVR's that previously only supported HDMI 1.4. Darn expensive for that but I knew that going in. And while the MDC module pricing is high, I really like my T777 AVR and I can't replace it with an AVR of equivalent quality for less than this module cost. But I was so exasperated by other aspects of my experience that I left detailed feedback about it with NAD. In brief, NAD makes it extremely hard to find the firmware update needed to install the card. This isn't intentional as far as I can tell. They used to have the firmware link right on the VM300 product page. But a month ago they redesigned their website and removed almost every bit of useful information that was there. So I chalk this up to incompetence, not corporate malfeasance. Once you manage to get over that hurdle you become aware that NAD has reduced the usefulness of the AVR software with its latest release. One problem is probably hardware-related: video overlays are no longer supported. Now 'Info' is only indicated on the T777 front display -- it does not appear on the TV. Also, the AVR menu, when accessed, replaces the existing video rather than overlaying it. Other functions like source table view are missing. And you can't reset the Audyssey calibration. All of this is a big, unadvertised, step backward in usability.

Pros: Adds HDMI 2.0a to older AVR's

Cons: Expensive Hard to find firmware Interface loses functionality from pervious releases

More details on the NAD VM300

Product Research


Professional Installation Required: To avoid impacting the warranty, the VM300 should only be installed by an authorized service center.

Compatibility: The NAD VM300 4K video module works with the T187, T777,  & T787 AV receiver; as well as the NAD M15 & M17 AV preamplifiers.

4K Video Module: The NAD VM300 allows you to upgrade select NAD AV receivers and preamplifiers that currently support 1080p video to ultra high definition 4K and HDR video (including HDR10 and Dolby Vision). It supports 60 frames per second (4K@60 4:4:4) to fully support all current and future UHD formats. The VM300 also includes the latest HDCP 2.2 copy protection necessary for accessing all commercial UHD video releases.

Note: Installing the VM300 disables all analog video input decoding from Composite, S-Video, and Component Video sources.

BluOS-Ready: The NAD VM300 also adds the option of integrating BluOS Hi-Res multiroom audio into your NAD system. A BluOS kit (sold separately) is also required.

Modular Design Construction: The advantages of a pure digital system are many, but one drawback is the constantly changing delivery formats for digital content. Each of these formats typically requires specialized hardware and software, often with licensed IP and content copy protection. For this reason, NAD places all digital interface circuitry on easily upgradable modules. NAD calls this 'Modular Design Construction' or 'MDC'.

[ Ryan  Mar 28, 2019 ]  Staff

[ Phil  Apr 20, 2018 ]

No longer have unit contact nad a Canadian company I am sure they can provide the best answers
[ GUY W  Apr 30, 2018 ]
Does the VM300 module support 4k UHD Dolby Vision? I have an Oppo UDP-203 player currently directly feeding my LG OLED65B7A TV. I would like to run the UDP-203 through my NAD T787 A/V recever if the VM300 module will support Dolby Vision like my Oppo player and TV will.
[ Larry  Nov 30, 2017 ]
1 answer
It does not appear the VM300 module currently supports Dolby Vision HDR content via the HDMI input/output. For more details or to discuss further please contact an Advisor directly by phone (888.955.6000) or online chat.
[ Larry  Dec 05, 2017 ]  Staff
Does the HDMI 4K support ARC?
[ Peter  Nov 23, 2017 ]
1 answer
Yes and no. NAD told me that they were working on software updates that make it work with ARC universally, but to my knowledge, it only works with some manufacturers. I have a Sony TV. It doesn't work.
[ Joseph  Nov 30, 2017 ]
Is this module compatible with NAD T785?
[ Leonard  Aug 28, 2017 ]
1 answer
The card may not be compatible with older AV receivers. You should check with NAD directly. They were very helpful when I needed advice or contact an NAD dealer.
[ Bruce  Aug 28, 2017 ]
Is this module compatible with NAD T775? Can't find that even on NAD website?
[ Todd  Apr 03, 2017 ]
1 answer
The NAD VM300 4K video module works with the T187, T777, & T787 AV receiver; as well as the NAD M15 & M17 AV preamplifiers. I'm afraid it would not work with the T775 though. If you would like to discuss further, feel free to contact an Advisor directly by phone (1-800-324-9695) or online chat.
[ Larry  Apr 07, 2017 ]  Staff
Does this card also support 3D video in 1080p?
[ Brad  Feb 02, 2017 ]
1 answer
Yes, the HDMI inputs/output are backwards-compatible with previous HDMI versions; and would all fully support 3D video at 1080p resolution. If you would like to discuss further, feel free to contact an Advisor directly by phone (1-800-324-9695) or online chat. Hope that helps!
