Are "vintage" DAC's worthwhile, or is this a tech that does not age well

@curlyhifi. Those Krell SPB 32x, Studio and Ref.64 dacs were some outstanding units!  Thanks for the audio flash back...been a long time since I had them but man did they leave an aural impression.  Oh boy, guess this guy is going to start hunting one down to play with again.

The old vintage dacs will sound absolutely wonderful but you will not be able to hook them up to all the new forms of digital equipment or computers but if you want to hear the best digital sound a vintage converter will stomp all over the new stuff no contest.

@devilboy 

yes, you read it correctly. You would however forego the opportunity to slave the server’s to the dac‘s clock as well as DSD and higher resolution formats. Using a OCXO or rubidium clock on the dac via USB has major benefits on the server. Alternatively there are reclockers for the USB connection only (e.g. Innuos Phoenix); they however do not benefit the dac.

...a vintage converter will stomp all over the new stuff no contest.

Yes, I agree with you.
Thank you and all memebers for comments and your opinions.

There was an almost identical thread recently.  You ought to look it up.  I wont repeat the lengthy post i made, but i will say:
1. I have no dog in this fight, yet.2. I totally disagree that DACs sound alike. And i run single blind experiments all the time.3. Some excellent old DACs still can equal or outperform many current DACs. I have two that do, from 1991 and 19994. Lots of DACs are datasheet engineered and suck. The fact that they get good (typically user anecdotal) reviews supports the hypothesis that its all snake oil. LISTEN!5. Overall, tat said, DACs have progressed steadily over the years6. Most advances int he last 10 years have been in up/oversampling algorithms and timing/jitter, IMNSHO.

BTW DACs have no wear parts to speak of except for electrolytic caps, typically only a few int eh power supply. So they can last a long time. The DAC caps are mostly ceramic and film which last pretty much forever.
