Roxy54,
I do understand the appeal of NOS and R2R chips and ladder topologies. I would just say that there’s more to the "big picture" viewpoint. I haven’t heard the Lab12 DAC SE but have no reason to question Teajay’s enthusiastic review.
A friend let me borrow his Holo Springs level III DAC so I could hear it in my system. As you know it is NOS and R2R discrete resistor ladder design. It was actually a very good sounding DAC in my 300b SET/DHT Line stage based system. In direct comparison to my Yamamoto YDA O1a DAC we felt that both were organic in nature, the Yamamoto was more ’alive, extended and dynamic in presentation . In reality more emotionally involving.
The Yamamoto is delta sigma(Texas Instruments 1794 chip) and over samples 8x (but with minimal digital filtering) no NFB or OP-amps. My only point is that you really have to listen to these DACs to judge their sound quality. Delta sigma versus R2R is only part of the story and I don’t believe that one can be declared superior to the other.
I hope you do get to hear the Lab 12 DAC SE in your system. Best of luck to you.
