Спасибо за советы, а вот еще теперь вопрос:
Если сравнивать эти 2 кита:
AnalogMetric DAC ("GreenDAC")
Второй кандидат это нонейм кит с ебей:(комплектация такая-же CS8412-SAA7220)
Нашел еще пару интересных китов, и похоже я сделаю свой выбор в их пользу:
DAC WM8805 + TDA1541 1.0J I/V output OS/NOS
Structure :
Digital and analog stage
input : SPDIF of multi-input (coaxial, USB, optical)
I2S input at NOS mode
WM8805 as digital receive stage + CPU control + SAA7220 + DAC TDA1541
to use audio low noise transistor and JFET constructed for the I/V converter.
2 nd stage use JFET as first class buffer output
Power regulation stage
Individual 2-stages regulation power supply of +/-15V for Analog, +/-5V for Digital
( transistor + op-amp construction )
Working voltage: 0-9Vac / 0.8A x 2, 18Vac / 0.8A x 2
Из той же серии, более простая версия:
DAC TDA1541+WM8805 NOS 1.0UI multi-input
Multi Input with select switch (software control):
BNC(coaxial), USB, optical, and I2S data signal
DAC kit construction:
1. Digital receiver : WM8805
2. NOS (non-oversampling) application
3. output from DAC TDA1541 directly, no analog stage (should work with driver stage)
Power supply:
0-9V*2/ 0.8A & 0-18*1 / 0.5A
PCB size: 210mm x 112mm with double size gold plated.
