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


Hello,
whether it’s worth looking into old dac such as
Spectral SDR 2000,
Mark Levinson No.35 (36)
or so Sonic Frontiers Sfd-2 Mk2 DAC.

Digital audio is the fasted moving, now improving category out there
Because to this day they have no usb connection or other options.
But is it necessary?
Or is it better to still focus on a truly time-tested sound?

@dsper, 
I would never try to make the cast that current production DACs can not sound good, quite the contrary.  My belief is that very high quality older generation DACs can be competitive and sound as good (In some instances better)  as a modern DAC. There exists a hierarchy of sonic qualities in both groups of DACs.

In my experience whenever the power supply of a component can be upgraded it's worth the effort and additional cost.i see no reason why this wouldn't appy to the Soekris DAC.

No issues charles1dad. Just trying to share a current live experience!

I guess it would have to be an external PS with the Soekris. I mean it is no bigger than a hard cover book you might borrow from the library (I use a Kindle by the way as it is wonderful when you are traveling).

My problem is trying to sort out that hierarchy of sonic qualities. For example, I believe that understanding the analog output of the DAC is a key. The technical explanation has to be translated into what this means to the sound. I suppose not all designers are totally forthcoming, and if you can find the technical information, I find my eyes start to glaze over trying to relate that to sound.

It is a conundrum between the plethora of choices and relating them to the sonic heirarchy to make an informed buying decision.

I think I was rather lucky that the Soekris sounds as good as it does.

And hopefully my grammar is better with this post!

Thanks for listening!

Hi @dsper,
Given the diminutive size of the Soekris DAC  I imagine the optional power supply is external. I would bet its use makes a positive difference.

To the OP and the question of whether it is worth it to buy a vintage, quality DAC - I would say yes if you can buy it for a reasonably low amount and/or it has been serviced and is in decent working order.  The early higher end DACs focused more on the tried and true principles - things like high quality power supplies (not wall warts or switching power), a heavy, inert  chassis, and the implementation of a quality analog circuit.  When D/As became a $99-500 commodity, these design principles went out the window and the focus was on the chipset and general architecture (ladder, R2R, etc).  The original designs put note emphasis on the “A” instead of the “D.”  Of course, a heavy, isolated, acoustically inert chassis is expensive, and good power supplies are expensive as well.  That’s why companies like Schiit and Denefrips focus more on the “D” side of the equation.

 There are current brands, obviously, that combine the state of the art on both sides of the fence, and they are predictably very expensive, and they sound great.  I’m listening to an EMM Labs DAC right now, in fact, and its mind blowing.  It replaced an also-good Lampizator DAC.  I was in the camp saying how great the Lampis were, how much smoother, etc - untilI got my hands on an EMM.  Steve Guttenberg reviewed the equivalent DAC from the less expensive Meitner line, the MA-1, and compared it with his reference, the Denefrips Terminator.  Basically he said there was no comparison between the two.

 So if you are game, it might be worth it to try either a really early, high quality DAC, or perhaps a newer (but still older) ~ 2010 EMM or similar.  You can get an early one for $3,000-$4,000 easily (compared to current ones at $16,000-$25,000). Much of the magic for a deep discount.

Hi @dsper,

I emailed Mod House Audio and Soekris in Denmark but so far no response about an external power supply. I searched both websites and did not see anyhting.
