Testing SID-chips on the C64 Ultimate - UltiSID, 6581, PDSID, ARM2SID - Stereo and FM

Commodore 64 Ultimate - Can I really hear the difference between a real SID and the clone ones? PCBWay kindly sponsored this video https://pcbway.com/g/sh5u2D great quality PCBs from just $5! I thought it would be fun to compare the built-in UltiSID with a couple of real MOS 6581 SID's. As I also got a few PDSID's, and a set of ARM2SID's, I tested them too. DISCLAIMER: I am not an audio or SID expert, and I am doing this for fun! Doing a comparative test is not easy - take it for what it is.
