Ima šta da se vidi: A/D i D/A sa 18 i 20 bita imaju isti dinamički opseg od 90dB, niži nego kod 16-bitnog CD plejera (96dB). Mene to navodi na zaključak da je analogna elektronika te kartice daleko ispod nivoa jednog 5532 i sličnih, što je danas neki minimum u audio tehnici.
Obzirom da se radi o PCI kartici, moguće je i da ima slabu EMI zaštitu, pa je računar i periferije "pune" uobičajenom mešavinom SMPS i ostalih smetnji.

Kao što rekoh, napravi test koristeći DAC kartice kao izvor, a ADC kao prijemnik (loopback), pa pogledaj spektar.

Pozdrav
