Some of you may have seen this already, but it was new to me and I thought it was pretty neat.

Cool video Lincoln, that's a pretty fancy tube.  Never heard of KR Audio before, I assume the tube featured in the video is ...something... like this:

Scroll down for the price :o

Gotta remember that 300B and 2A3 valves are typically bought by audiophiles who want low power single-ended-triode amps powering their ultra-efficient speakers.

Cheap bastards like me are more likely to consider ST70 clones that use EL34's. They're pentode, which audiophiles seem to consider dirtier than triode.

Agreed. I wish I could afford to build the Bob Latino ST70 and the Crites "Cornscala." for 2 channel listening. None of this is true audiophile but I think I'm more interested in impact and feel than in pure accuracy. I'm also interested in picking up a pair of the original "Large Advent" speakers to pair with my 20wpc Marantz. And I would love to own a pair of Bose 901's. There, I said it. But it doesn't matter because I can't afford any of it anyway. :)
