I doubt Ken had antisocial PD. He had personality features possibly of some other PDs, but there isn't enough here to say more. Having a dysfunctional relationship with his older son is unfortunate, but not enough to make a diagnosis of anything. His son wanting a vintage car his grandfather owned and a vintage turntable as his only bequest is telling of not much, except that it was met with a smallness of spirit by someone who could have afforded to do better. The unsaid part may be bitterness over how unhappy his mother apparently was due to living in a home Ken dominated, but that is speculation. It is hard not to wonder whether he liked things more than people.
He built a big sound system of his own design, choosing a big line array design and using his experience in commercial polymer molding to build it, filling in with extra low-end speakers and driving it with stacks of Krell amplifiers and separate crossovers. The video suggests he enjoyed it even if he realized it wasn't perfect: "you lie to yourself and tell yourself it sounds great."
The grandfather clocks are an oddity, though. They aren't particularly great at timekeeping, they are delicate and cumbersome, and not anyone's idea of modern room accent. These weren't antique clocks which might make an interesting piece in a modern room, they looked like reproduction pieces.
