Product Description
Well reviewed on Head-Fi, HiFi Insider, and beyond, the Massdrop x Grace Design m9XX was inspired by the world-class m920 DAC/amp—offering the same performance level for audiophile applications, now at a far more accessible price. Working with Michael and Eben from Grace Design, we stripped the m920 of its lesser-used pro audio hardware and improved upon the audiophile features where possible, all while retaining the high-res DAC implementation and super-clean solid-state amplification Read More

When I plug in my power cable now, I'm greeted with OC and it flashes OC. I guess there is a power issue, anyone had this?

Hey Everyone! :) I'm sorry for sounding like a major audio newb, but I've owned the M9XX for a few years now and in the near future I'd like to setup a new desk with some nice speakers. It would be lovely if there was some way to use the M9XX to drive them but also use some kind of audio switcher like the 4 channel AMPs on Amazon to be able to switch between and ideally adjust the volume independently for the audio outs (e.g. desktop speakers, monitor speakers, and *maybe* two pairs of headphones). I think I can chain together a 4-channel amp with the M9XX using an appropriate cable, connecting the regular 1/4 inch output jacks in the front of the M9XX to the 4-channel amp's input. In that case, I think the M9XX would be functioning more as a DAC than an AMP then. I'd be concerned about degradation in audio quality if I didn't also use a high-end amplifier on the output, but I'm really not sure if that's a concern. If anyone has recommendations for how to make the M9XX work with that or a similar decent dac/amp product that would do that, I'm all ears. I realize that the M9XX might be somewhat overkill for what I need--I listen to "high quality" audio from Spotify and own a pair of Fostex X and Sennheiser HD 300s. Desktop speakers forthcoming. While I wouldn't want to part ways with the M9XX I'm really sick of switching audio sources using the Windows sound settings. Thanks for your kind help in advance. <3

I see no one has answered your question. In case you're still working on your new set-up. A monitor controller might be what you're looking for. Powered speakers/monitors should be easy to connect. Passive speakers will require an amp. Connecting an amp into the set-up might be tricky. To power passive speakers you might have to substitute the grace for a different dac/amp combo. Topping and smsl have some offerings in that regard but I don't have experience with them.

Thank you Hanis! :) that definitely helps. I'll look into the monitor controller.

Anyone ever had the problem that the Device isnt recognized by Windows 10 anymore ? (From one day to another) Per default the Device was working with the Windows Drivers, but for some Reason the Device isnt recognized any longer by my PC. Re-pluging the m9xx only brings up a popup that "The Device isnt recognized by Windows". I tried also to use the XMOS driver provided by Grace but same problem. I also checkt the m9xx settings e.g. U2 is set ... Any suggestions ?

I bought this product during the original drop, and out of curiosity was browsing Grace's website today, where I learned that there is a firmware update for the m9xx. I'm a Mac user, and the site states that the DFU for Mac is "Not Available".... is there such a thing as a firmware update tool for Mac that allows one to update the firmware of any device connected to the Mac? Thanks for any help.

Do you think you could share that link? I've reached out and haven't heard back yet most likely due to the pandemic.

Here's what they sent me... I just tested the link and the file is still there. "We have an OSX DFU we've been testing. It can be downloaded from here: https://drive.google.com/open?id=1TsGtn8_A-lMMWiQlAu0Q6APJv5lRGzYM It is not properly signed yet, so you may need to right click on the application and select open for it to run."

Kind of new to hifi audio. Would this be a good match for the HD58Xs?

honestly you're better off investing that extra money that the m9xx costs into a better pair of headphones and get a cheaper dac/amp. Most budget dac/amp combos have enough power to drive most headphones, bar some planars and a few really inefficient ones. I think you'll get more mileage for your money by investing in a more expensive headphone at this price point. But yes it's a fine match, I've owned the m9xx for a few years now and I've had no complaints. On high gain/power it even has enough juice to run even my famously inefficient Argons mk3s comfortably

old old old thread but... I bought new speakers, vanatoo zero's, which are USB based. When I connect the Grace m9xx they cut out. I have been unable to figure out a config where both the speakers and the m9xx's work. Suggestions?

Why is this on sale for the same price on Amazon right now? It doesn’t have the collaborated with mass drop description though.

Grace created their own standalone version that is exactly the same except for one added input on the back, an S/PDIF coax.

Man but the panda stack is so pretty and at $300...but Ye I saw all the reviews on the nfb11. Wonder how it does with iems tho..he never mentioned that. Specs say output impedance 2ohms which is very high

I tried few IEMs with my unit. Nothing crazy expensive. I had 4 driver Trinity IEM for about 200 and few less expensive units. Zero noise. Everything seemed fine. But I have not done too much listening with IEMS.

I have two questions. #1 Are the RCAs on the back outputs or inputs?
#2 Has anyone used this with an Android source? I know I tried the M920 and couldn't get it to work with my NVidia Shield Android TV box.

#1 They are outputs. I currently use it as an external DAC with the CTH. #2 Haven't tried it.
