All information: http://www.totaldac.com

 

Semi DIY DAC, available fully built at EUR 3850

 

Discrete components DAC: R2R DAC with 0.01% Vishay foil resistors

Clock and anti-jitter FIFO: it uses a buffer memory (FIFO) to store about 10ms of audio data at the digital source rhythm and output a stream at a local oscillator rhythm.

Active crossover configuration possible.

Created his own R2R from scratch.  NOS.  Jitter rejection from all sources.  Sounds promising.  Would love to hear it.

Considering a Berkeley Alpha costs about as much, that is seriously tempting in that budget range.

IMHO, its biggest weakness is the lack of connectivity, although it could be remedied if you can DIY.

On the other hand, considering it s price of parts/ price of finished product is outstanding.

Looks amazing, way out of my price range though!

And of course balanced outputs would be nice.

That is one sexy DAC!  All those z-foils are giving me wood.  The $5500 is bringing be back to reality
