BP50 analog passthru or does it use an ADC?

Does the rca analog in or the phono in go thru an ADC (analog to digital conversion) stage? or is it true analog passthru?

essentially is this a pure digital preamp? so everything goes thru the ESS9023?

i’m not saying this is bad, just want to clarify if using analog in is worth it?

It’s not. You can apply effects to it, so it goes through the DSP and DAC.
