I find this article to be in extremely poor taste, especially being so 1-sided and so soon after the man's demise. It's a family's dirty laundry that didn't need public exposure. Sure, it looks like they had real issues - if the epicenter wasn't the damn stereo, it would have been something else.
Calling it a "cautionary tale" is so tacky. It's more like fodder for the usual rubber-neckers and high-end audio detractors. There's no lessons to be learned here. Live well and try to do better by loved ones? Was already aware of that one, thanks. Reality is always so much more complex than that.
Anyways, RIP Ken.
