I’ve found this DSD DAC, has anyone used it?

Thank you in advance.

Thank you in advance.
Thought Holo uses two separate resistor arrays, one for PCM and one for DSD?
However, now that I think about it some more, could be there is some manufacturer who tries to use a shared resistor array. Thing about this dac is they don't say if it plays PCM, nor do they say the maximum sample rate.
Anyway, for about the same cost it should be possible to build a MarcelvdG RTZ DSD dac. Then as time goes by it should be possible to step it up to higher and higher levels by adding better external circuitry. Main reason I can think of not to do it that way might be reluctance to do SMD soldering.

Its probably a 2-layer board, whereas you really need at least 4-layers.
It doesn't have enough proper voltage regulators, especially for Vref which is critical to good sound
It only has one clock.
There is no reclocking circuitry after the FPGA (FPGAs are jittery and DSD dacs tend to be sensitive to jitter)
The resistors are probably cheap, most likely have high excess noise (current noise) which will blur the sound.
There is no schematic or documentation so it may have be reverse engineered to figure out how to make it work.
It doesn't have a proper output stage.
The output switch ICs don't appear to have any bypass caps.
For about the same cost you could have a far, far superior DSD dac (if you can assemble it yourself).
