@fauguy the PCM upconversion cannot be done via the remote only via the mode button on the unit itself so "on the fly" changes aren't possible. For now I have settled on the 2Fs setting on PCM. On my player there are 3 filter settings for DSD (SACD) playback. The cutoff frequency becomes progressively lower from F1 to F2 to F3. Mine is set on F2. I think one could get hung up on all the oversampling and filter stuff. The player sounds wonderful with the native settings. The new model 10 from Marantz looks interesting and it would be interesting to compare it to my K-03XD which new was discounted to 12K from my dealer.
