ODAC is supplied by a Salas BiB and sounds super-fantastic! My best digital source ever had at home. The voltage output (2V) from the ess9023 inside ODAC is directly fed to the preamp through a short lenght of DNM cable. No I/V stage nor other circuitry between dac chip and pre.
Oh ok. Well there's I/V conversion somewhere, i guess it's integrated inside the ESS9023 chip?
