I recently purchased a Edifier 360DB connected to my dac Fiio K3 with a QED coaxial cable, and when I upsample to 96 hz, I don’t hear any sound, but if I don’t upsample and I play a 192hz recording , the sound is working properly. This does not make any sense to me since I know that the issue is not with the cable, which is excellent, but with the upsampling. I do it in PCM since I already know DSD doesn’t work with coaxial cable, so I’m clueless. Does anyone have any idee please ? Thank you.
