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. 

Speaking of R2R just picked up a 20 year old Audio Note Dac-3 Signature which uses a K grade BB PCM63 chip which is I believe R2R. It sounds utterly fantastic.

If you care to look/study and compare most dac chip manufacturer data sheets are adhered to for implementation, even some (hiend ones) using even the exact I/V stage and buffer stage that’s on those data sheets.
"Some" (me, Audio Note above ) use different I/V and buffers, but as far as dac implementation itself they nearly all follow the data sheet protocols.
But doing discrete with this topic that's another thing again.

That Terminator DAC does look pretty serious! Thanks for sharing George... Are you going to pursue this one?

Wish I had the funds.
