how good are the non os dacs?

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

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

Thanks!
Alex

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.

muralman,
as i am no engineer, what seems to be the concern in the design of the dac. i respect your hesitation and would like to hear what you think is a problem.

I am fence sitting right now. Though some of the detractors don't care for it, the TD A1545A chip is OK with me. It is the asynchronous reclocking that gives me pause. Some folks well learned in electronics theory don't give this type of clocking any credence.

I would love to try it against what I have, but this Malaysian company does not take non-defective returns. That means I am stuck whether I like the DAC or not.

Critics of the NOS sound are listening to something I never have had the displeasure of hearing for myself. OS is often grainy, and bright. NOS DACs are not grainy, and the highs can be extended and very sweet. It is true some builders roll off the highs to the benefit of seductive mids, but that is a designer's choice.
