how good are the non os dacs?

had the epiphanous vinyl experience and realize that i would like to bring my digital closer to the vinyl qualities i.e. smoother with more natural tones but retaining good resolution. i have my eye on the non os dac by promitheusaudio.com. small company but the opinions thus far are great. could a few of you digital experts comment on how good non os really sounds? love to hear recommendations from those of you that have listened to them in comparison. thanks

so, thus far you guys are very happy with the non os dacs. that is a good recommendation towards that direction. can anybody check out the promitheus website and tell me if technically this dac looks sound. saving 500.00 vs the audio note sounds good to my wife and the checking account. thanks.

"Addition By Subtraction"; this is the best description about NOS DACs I can provide.

It is due to the fact that NOS DACs 20KHz sine wave looks like a ladder. This means that the top extension is smeared, resulting in lusher presentation. So many audiophile like this, so it is not necessarily a bad thing.

I'd vote for OS though. :-)

My NOS DAC excels in hf detail, including spatial clues.

Would you please elaborate? What make is your NOS DAC?

Thanks!

Alex, there is nothing smeared nor lush about my system sound. Layers of detailed sound are carried riding on a supremely musical sound. My highs cannot get any more airy.

My DAC is a one of a kind built on an Audio Note circuit board.

I changed my mind about the Promethius. Upon studying the board, and
correlating research in DIY forums, I would be very wary of this DAC. I may still
consider buying it, but there will have to be some more positive reading in the
future.
