IME, having a stepped attenuator installed into the input stage of my amplifier gave me the best sound I heard in my system. I've tried both active and passive preamps, both colored the sound more. I've actually had increased dynamics, soundstaging, and frequency extension this way. No thinning of sound often encountered with passive preamps and no veiling of sound often heard with active preamps. Sorry for off topic remark.
Getting back to OP question, a friend of mine got the Lampizator DAC which uses computer controlled resistor based volume control. Sounds quality of the DAC is excellent.
