Is this compatible with PS5?

A good update to this Grace SDAC would have a USB-B input, because the micro usb is too fragile and a digital input as on the Grace SDAC balanced without the balanced output. And the original unbalanced output.

I am pretty new to this depth of audio interfaces, but I have a problem and I think this is the fix if I'm understanding right. so my problem is at my church, our new computer Mac Pro 13" when connected to our sound board (Allen and Heath QU16) with a straight 3.5mm to 1/4 jack, it distorts higher sounds such as piano keys at the 3rd C and around that area and higher up. The same problem happens on my personal Mac Pro which is a year older, but on my iPhone 6 and 11 the same song will play perfectly. I have tried volume adjusting at the source of the music on the software, I've tried the volume output on the Mac itself, and lower volumes on our mixer. (for reference the mixer has EQ and this doesn't fix the problem, and the gain is normal I have tried moving it as well, and I am a pretty decent mixer with anything else on the board). Any help is appreciated!

Yes they both have USB-C out, and we use a multimedia adapter with usb 3.0 on them, I’m not sure why the sound isn’t as good but I have used a Presonus Audiobox USB, and when using headphones output it fixed the issue, so that’s why I thought this would work

Did you use macbooks 3.5mm output or plug it in to the Dac? And the iPhone? A MacBooks dac supposed to be pretty good so you can feed it direct to amp. The new iPhone don’t have a 3.5mm so the Dac is good there

Dear All, I am planning to buy this fine little DAC, but I have an older computer (X58) which only has USB 2.0 not USB 3.0 on he backside. Will this cause any issues, since USB 2.0 can provide less power and less data transfer. Thanks for your anwser in advance.

2.0 should be fine, it is the version usb isochronous music transfer protocol was based on.

Looking for some help about this, I just purchased the massdrop x Hifiman H35x and I'm trying to figure out if I need to get an amp with this dac. The H35 only is at 19ohms so I feel like the dac gives more than enough juice however, if I plug in these headphones into the dac directly will it help or hurt my headphones? Also would it sound better if I were to get an amp? Please help!!

The quick answer, DACs aren't meant to deliver power. DACs typically have an output impedance around 80 ohms. What this means to you is that only 1/5 the voltage will reach your headphones of 20 omhs (20/ (80+20)). It also could affect the frequency response and overall sound quality of your headphones but this isn't easily explained. You probably would prefer the sound through an amp but like I said, the DAC without an amp changes the frequency response of the headphones and perhaps more towards what you enjoy. I'd like to think using a DAC to power headphones wouldn't be damaging to the dac (certainly wouldn't hurt the headphones) but no guarantees from me. Your headphones are easy to drive. Even with only 1/5 the voltage of a 2V max rms DAC it probably does get plenty loud (around 107 dB sound pressure level - enough to cause hearing damage if exposed for too long). For reference I don't think I listen to things above 85 dB spl.

Indeed. With the HE-35X your mobile phone should be sufficient, unless you have harder to drive and/or more resolving headphones. If that's the case then having a dedicated dac and amp would definitely elevate your listening experience. On that note, do ensure to look at sensitivity specifications as well

The DAC arrived today. I plugged it in and the light turned on but there is no sound. It is shown in device manager on windows, but I'm completely stuck. If anyone knows what could be wrong, it would be much appreciated. Thanks.

I ended up getting a replacement and it works fine now.

Glad it's been resolved! Are you enjoying it so far? :)

i had a newbie question, can this DAC be paired with a regular amplifier to run a pair of bookshelf speakers or is it only designed for headphone amps?

Yep it can! Be it into a headphone amp or preamp or power amp or integrated amp or straight into active speakers (although I'd recommend the balanced version for that purpose)

That is exactly how I use mine. Digital source -> SDAC -> Stereo amp -> Bookshelf speakers. It works great.

Sheesh this is so clean and minimal. I'm wondering what set of nice and neat cables I can use to stack this DAC with the O2 headphone app?

you could make your own very easily! You can use this method to create RCA which would be a LOT easier https://www.headphonesty.com/2019/04/guide-creating-y-split-braided-cables/

Hi, my SDAC randomly gets disconnected from my Macbook Pro 16". I try changing USB port, three different adapters (two of those is powered), and using one port/adapter exclusively for the SDAC. The adaptors I tested are: my dell monitor, an Aukey USB-C hub 4 ports, Vava 9-in-1 adapter, Anker powered USB 3 hub. Any hint? I couldn't find a support page for the product. Thanks

@Maxidw Same here. I read a previous post from @omcnoe which find a resolution: https://drop.com/buy/massdrop-x-grace-design-standard-dac/talk/2659283 But it's not working for me And another one here: https://drop.com/buy/massdrop-x-grace-design-standard-dac/talk/2661105


@Michael_Grace Please advise! It make not sense to do these workaround/hacks to make the SDAC work constantly. Thanks!

I had this same issue, now I have the SDAC on a simple adapter that only has a single USB 2.0 port (so no active circuitry, just a pass through of the USB 2.0 pins) and have had no issues since. It's something about these complex adapters with multiple ports that's screwing with the SDAC.
