I've read your posts for years. I note that you haven't posted anything on your "virtual system" for awhile. (I too need to update my system(s)). It's on my list.
I've seen that you're a Lightspeed passive preamp fan.
I've just discovered the wonders of the Burr-Brown PCM1704 (HiFiMan 801 as the DAC!) and just saw your post that you keep finding Burr-Brown chips to be naturally apealing. Me too.
I too have accepted that Duke has great insights, creativity, ears and engineering and I have his Audiokinesis Rhythm Prisms.
So what DACs and DAC chips are you using now.
Best,
Tom
