I must agree Modi MB stands tall among cheap dacs.
I'd like to build one of those, what did you use for a case?It was mentioned before in this thread but I'll repeat the recommendation for the Khadas Tone Board. It's a bare USB + coax SPDIF dac which goes for around $100. Even with case and power supply, one should be under $150, unless one goes with a very expensive power supply. It punches way above its weight and in my system and friend's systems seems to be competitive with DACs going for much much more.
I run mine "au naturel", i.e. just the bare board sitting on a piece of cardboard.
i now have 2 of these. one at work and one at home. super detailed. i did buy a case advertised on amazon but it was super cheapo: plastic broke as i was trying to assemble it (plus no real instructions for assembly):I run mine "au naturel", i.e. just the bare board sitting on a piece of cardboard.
You can buy acrylic cases for between $14 and $30. Amazon used to have the cheap one but I didn't see it when I just looked. It is available on Aliexpress if you don't mind buying from overseas.
gary,One neat thing about the Khadas is that it doesn't draw too much power so it's possible to run it off of batteries. I've tried using a 13000mah power bank and after 12 hours the battery isn't even 1/2 discharged. I haven't done rigorous testing but I think the battery sounds better than a simple switching power supply. A good power line filter that prevents switching power supply noise from getting into the other stereo gear narrows the difference considerably.
The Khadas allows you to wire up an external 5v supply and it will automatically take power from that in preference to the USB, so that's on my list of projects. But it sounds good enough with the power bank that I'm not in a big hurry.

Doug,. . . didn't realize you can use that spdif input . . . have you tried both? comparison?
Correction - I only needed a standard USB to USB-C cable, which already came with the Khadas. And I had a portable netgear travel router which was easy to hook up as a wifi-ethernet bridge. So I did the following comparison.. . . but it would be a big project to get it working. I'd need to hook up wifi to the Microrendu and then pick up a USB-B to USB-C cable before I could make the comparison. So it could take a while before I get around to it.
Cool; thanks for giving it a try!Correction - I only needed a standard USB to USB-C cable, which already came with the Khadas. And I had a portable netgear travel router which was easy to hook up as a wifi-ethernet bridge. So I did the following comparison.
1) Modified Squeezebox Duet to Khadas via spdif. Squeezebox hooks up to my music server via wifi.
2) Sonore microrendu (with linear supply) to Khadas via USB. The microrendu is set up as a Squeezelite endpoint, i.e. as a Squeezebox. The microrendu hooks up to my music server via wifi, with the netgear travel router acting as a wifi-ethernet bridge.
And the winner is . . . Microrendu to Khadas via USB. Sound is a bit more 3 dimensional. Whether this is due to the USB vs. SPDIF inputs or the quality of the Microrendu vs. the Squeezebox is an exercise left to the reader.
You're welcome. And thanks for prompting me to do the experiment.Cool; thanks for giving it a try!
