Re: DIY DAC
co je SNR?
fikus pise k lampizatoru s 6N16b v SRPP tohle tohle:
For HEAVY LOAD systems - like for some types of U-Out DACs - there is a
recommendation to use low Ohm load to bias the DAC output.
Then C4 and C10 must be large - 20 uF or even larger. So we are forced to use
electrolytic caps in series to keep bass at flat level.
We supply the best dry electrolyte polymer caps which we found to be most transparent
for sound. (Oscon, Sepc, Nichicon, Tantalum or Black Gate).
The ratio of (R4+R5)/R5 must be kept the same as described before (between 5 to 7)
but the R5+R4 must be kept around 1,5k to 2 K.
As an example: for AK4393 DAC use R4 = 1500 , R5 = 330 Ohms, C4 = 100 uF/6,3V
The same for ESS sabre dac.
