I had to check I wasn’t fooling myself on this, but no.
I’ve just got hold of a Project Pre Box S2 Digital that handles up to 256 DSD, so I set the upsampling to 128 DSD (my ageing server can’t quite make it to 256).
It’s reversing the channels
E.g. Marta Gomez Lucia - the backing guitarist switches to the left. Ditto the ‘ting’ early in Oleta Adams’ Get Here. To check I switched upsampling off. Both are on the right again. I then switched on PCM upsampling and they stayed on the right. So it’s only on DSD
Any thoughts? I’ve looked through every setting I can think of on the S2 and in Roon. Probably something obvious, if so I’ll hold my hands up
