I am loathe to throw stones as I certainly can obsess like any other audiophile.
That said, no I'm not OCD as that guy...at least not in the same direction.
And when I see the super tweaky lengths many audiophiles go to in their system I'm glad I'm not THAT obsessed with every aspect of my system.
It would drive me nuts.
But I have to be clear: that is not a judgement of other audiophiles that do go all out, like the guy in the video. That is only an expression of my own personal values. I just wouldn't like to be that tweaky.
BUT...if someone else ENJOYS the time spent tweaking everything possible, then that's what matters to him, and good for him for having fun. The guy in the video seems happy, so I would not judge his time mis-spent in that regard.
