Sorry, I should have been more clear. I meant the upsampling that a Mac does with ALAC. I actually use Apple Music and connect a MacBook via USB to the Lina DAC. I love the upsampling to DSDx2. I discovered LosslessSwitcher now which automatically ensures that bit-perfect ALAC is transmitted from the MacBook to the Lina DAC. 6V is very revealing how much SQ is degraded when Apple Music converts a 44.1 kHz file to 96 kHz. At 2V I somehow preferred upsampled 96 kHz to be fed into the Lina because it sounded cleaner when I turned up the volume. But there was so much detail missing I discovered later with 6V.
