Of all high end electronics, Burmester was the most opulent to me. Here is a pic of some Burmester components, a couple of Burmster pre-amps and the $74k Burmester 909 on the bottom:
That amp is rated as stable down to 1 ohm, with output of a bridged channel at 3,200 watts for a 1 ohm load. Its a solid performer, and the nicest amplifier I have ever seen, however I wouldn't pay $74k for it.
