Getting a bit confusing here, "discrete dsd" vs. native dsd........
From Jeff Zhu, the dac designer :-
"If Spring works in ’NOS’ mode. There is no oversampling, no conversion, just the original data doing the final digital to analog conversion..........I just explain how Spring can do ’discrete DSD conversion’. Actually it is like DCS and CHORD. If you looking to DCS and CHORD’s pcb, you will find ’discrete DSD conversion’ is also using
switches and precision resistors, like resistor ladder dacs. So, no matter it is ’discrete DSD conversion’ or ’discrete PCM conversion’, they all use the same discrete devices. Just work in different architecture. That makes possible to combine these two modes in one device."
