Works great with Qnktc AB1.2 DAC up to 24/192

I am playing High Rez files up to 24 bit 192Khz without any problems. But with big files...go into mpd config and choose to buffer 30 % before playing. If u dont do that....it will click a little bit in the sound the first 5 seconds. Also adjust buffer size up a little bit. All in all, with these small tweaks it works great.

Uh, I didn't know this open source DAC (very interesting indeed), thank you for the feedback. Which platform are you using, Rpi or BBB?

[dopus]

Through usb hub connected to raspberry pi. Usb hub for extra power. The dac is usb powered only so running it through rpi^s usb did pull to much power and the freezed up. With powered usb hub it works great. The dac is open source, its easy to modify, it sounds great for the price, its not expensive,it is async usb ,it supports up to 24 bit/192Khz

Seems this DAC uses a Atmel AVR32 MCU programmed in open source C as USB controller. Interesting and probably a lot of more work than using a hardware USB controller chip.

Looks like they have changed the name of the dac to Henry Audio instead of Qnktc. Dont know why...but it is the same dac , and specs. Only new name.

What do you think about the new Henry Audio?

Do you think that its better than Modi 2 uber?

I do not know what to do


Thanks!

I have the Henry Audio Mk1 and considering setting up a raspberry pi 3. And excuse my ignorance now, but I would preferably use an ordinary usb-hub to power the DAC? Should I also consider any special power supply for the pi that increase power stability for the purpose of audio? (I failed the electricity part of physics in high school )

Hi GAP,

but I would preferably use an ordinary usb-hub to power the DAC

The question is, what is a "ordinary usb-hub"?
If it is a powered one then you do not need a special power supply for the Pi.
The Pi3 on the other side consumes more power than its predecessors.
The Pi Foundation approved power supply has 5.1V with max. 2,5A.

Thanks Frank!

I bought a 2.5A RPi power supply I will use. And haha, yes with'ordinary' I meant a powered bus. I hope I won't need the hub though.
