Classé new Delta pre-amplifier with DSD capable DAC
Description Of Issue
Input: DSD64 with EQ on
When I choose DSD output mode, it seems upsampling only occurs after EQ. But ideally EQ should be performed on already upsampled signal?
This seems so when I choose PCM output - bit depth is only downsized from 64 bit float to 24 bit after EQ. On the other hand, signal path shows the high rate 2.8M signal was downsampled to 384K before entering EQ, which might cause some loss?
Under such circumstance, I don’t know which setting is better . I reckon DSD output is better for original DSD music?
The crux of my question is if there is any hidden upsampling and downsampling process happening within the EQ work which is not shown in the signal path .
