Re: more details please
Voltage out
TUSB3200A for USB interface
AK4117VF for digital audio interface
AK4396VF for audio DAC
OPA2228U for audio output stage
PGA2311A for volume control
I am more curious about the PLL

About PLL
mDAC-2v has 2 PLL in the circuit.
One for USB interface(TUSB3200A) and the other one for DIR(AK4117).
When use USB audio interface, PLL in TUSB3200A and F/W make USB jitter cleaning function.
This F/W control jitter cleaning function can remove low frequency jitter and locking speed is very fast than analog PLL.
Result of jitter cleaning function, sound quality are great imrovment.
SRC based jitter cleaner change the digital audio data.(because resampling caculation)
mDAC-2v jitter cleaning function never change digital audio data.
It is true bit transparent D/A conversion.
If you use mDAC-2v with your PC, your PC become a great audio source.
mDAC-2v unit price is 500,000 KRW in south korea.
It is 474.38 USD
Todays 1 USD exchange rate is 1072.44 KRW.
Thank you.
