Today I wanted to cover a couple topics that have come up in the comment sections of a couple of my videos. I want to test Op-amp swapping, see if I could discern differences in the sound and most importantly if I enjoyed the change. I also wanted to demonstrate how simple these are to swap so we will cover the disassembly and installation of the Sparkos dual discrete SS3602 into a Fosi BT20A Pro. Will this be magical beans or Musical Bliss?
