E1DA PowerDAC, 9038S DAC или свистки счастья

[dendra]

Новых поколений пока не предвидится?

Предвидится:
Cosmos DAC. Dynamic range 130db(A) THD+N/sinad 122-123db or 0.000075% i.e. less than APx555b can measure at 6Vrms. Cosmos ADC has balanced XLRs Lef/Right 6Vrms outputs + unbalanced 3.5mm HPA output.
Cosmos DAC so far I plan to use dual 9038q2m for following reasons:
1) cost effective, especially today when all silicon parts got 3x price, hence 9038pro could cost about $150/chip
2) the same time, dual 9038Q2M can provide THD+N/sinad level at the edge of what able to measure the most precise audio analyzer APx555b. 9038pro may have extended dynamic range but practically 130db vs 140db difference is not critical at all and couldn't cost $140 extra
3) dual 9038Q2M has moderate current consumption and could be powered with a single USB3 port, 9038pro draws like a horse and USB3 port power will need some external Y-splitter help
