From a few of them:
threatened to drive one of our sponsors out of business

gave vendor enough grief to make that vendor redirect energy to him than the tasks at hand serving the audiophile community

***this was one of my favs, but I'm sure that what ever 'grief' I dispensed was required at the time. As far as 'serving the audiophile community' goes, as a memeber of that community, I don't remember being served at all, let alone poorly.

Either way, I am going to continue with building myself better audio. Anybody who wants to come along is quite welcome.
cheers,
Douglas
