Yes exactly, the minimum phase filters are usually done over DSP but some like the Schiit Fulla and Jotunheim DAC portions use analog filtering. These are cause the destruction of stereo width and imaging with minimum phase filters. Of course it is applied to both channels, I don't know why that was brought up at all earlier in the thread. Anyways on a DAC with switchable filters, is easy to hear what the minimum phase filter does (collapse stereo width/imaging on recordings), why it does it (not time-domain coherent), and how it does it (some frequencies are delayed more than others going through the filter). If you have a decently resolving, high-fidelity system and not closed headphones, bookshelf speakers on a bookshelf, or one of those bluetooth amazon/apple pod egg things, it is pretty easy to hear with a DAC that has switchable filters. As for the psychoacoustics behind it I don't know. Family Feud style internet sampling done by Archimago? I don't care.
