Any device will upsample if it gets a low-frequency (44.1 or 48kHz) signal at the input. You can not select this, it will always happen, I am convinced Ronnie is correct on this. I can hear a clear difference between the 'old' upsample filter and the apodizing one, and changing 'HS output' from Y(es) to N(o) did not make any difference.

No, it depends on which device performs the upsampling and which filter it uses.
