More discrete R2R Mulibit dacs.

I use an R2R in my dac but that is where the similarities end.  It is like saying a preamp uses 6DJ8/6922 tubes but one company uses the Amperex tube brand.  It comes down to the component design.  My power supply weighs in at 30lbs and I use DHT design.  So while the R2R may be better sounding, it still comes down to the design and implementation.  If it was just the R2R, I could make a DAC for $500!  There are plenty of good sounding DAC chips available such as the Sigma 32 bit for one.

Happy Listening. 

George thanks but when I say implementation I am talking about the total design.  The DHT DAC that I build has a 30lbs power supply.  A little different than the typical DAC chip or R2R implementation.  Tube rectification, tube rectifier, current limiting, etc.  Most people think I am showing them a power amp when they see it.

There's always the Analog Devices AD5791 that's used in the Schiit Yggdrasil. Granted, it's only 20 bit, but it's still a true R-2R ladder. And expensive at minimum $60 a pop.
