Default WTB - Balanced vintage DAC

I'm looking for a mint vintage DAC that has balanced outputs. Currently interested in the Parasound DAC-2000, Assemblage 3.0/3.1 and Sonic Frontiers SFD-2 MKIII. The thing should be in absolute mint condition and seller willing to ship worldwide. Please let me know if you happen to have one of them. I'm willing to listen to any other option.

TIA.

You might want to look at the Audio Synthesis DAX range, no longer in production but should be available second hand.


For the best reproduction don't use SPDIF it has lousy stereo image and bass
The best way I know of to transfer digital is lots of hard electronics work using
flip flops to individually transfer DATA BITCLOCK and LRCK to the DAC oversampling
filter where flip flops are used to clock those same signals in again. I did this in 1997
and had an article published in Wireless World. But I warn its lots of hard work and very unconventional.
The Deficiencies of SPDIF as a Digital Transmission Method

The use of a DBX type 1 compander though is much easier, and remarkably has a similar effect with improving bass and stereo separation.
Once the audio emerges out of the DAC, use a Type 1 DBX encoder like a 180a or 155 or my favourite model the 150x available on ebay in tandem with a dedicated audio hard disk recorder like a Yamaha CDRHD1500 enabling storage of 500 hrs or more of audio, and with the DBX , gaining the advantage of 20db+ dynamic range - if you use balanced connections. You also have to be quite patient recording your CD's real time, and would need a balanced to unbal conversion and back again to use the Yamaha or quite a bit of very fiddly work on the Yamaha board to make it fully balanced in and out.

There might be other ways, but this is the best I have found.

Cheers / Chris

Thanks all. I think I'm pretty settled on the Assemblage 3/3.1 or Processor 3. If you have one, I'll take it from you
