I’ve found myself in need of an Oppo player or Universal player. To be honest, I never have heard of either until this year. Primarily for Sacd multichannel, which I need to figure out as well. Also I’m DAC illiterate. Do I need a standalone DAC for these or are they integrated? I just want to hit play and hear music from all four+ speakers going into a line aux on my amp. It looks like Oppo is no longer, so which used ones to look for? Or what current Universal players. Is this another dying category?
