the prices!!. No wonder people want to roll their own...

Those may be "old stock" tubes which aren't made anymore. Since there's no new supply, the prices will be higher - when they're gone, they're gone for good.

But the real trick to good sound is the cable, amirite?

Yeah, they're about $20 a pop. http://www.thetubestore.com/shuguang6146.html

This is the exact tube they show in the pictures at HardOCP: a Sovtek 6922.

Ahh, excellent link. From the photos, we can see that the tube is a Sovtek 6922. Google tells us that thetubestore.com calls the 6922 "Sovtek's premium version of the 6DJ8." Which everyone should recognize as a dual triode. Data here tells us that it has 6.3V filaments (perfect for coexistance with any 25120's that may be required by future DRM schemes), wants 90V B+ (plate voltage) and has a max Plate Dissipation of 1.8W.

This is a preamp tube, which is appropriate, actually. Get those nice GloFET harmonics and then feed it to some decent SandAmp for actual power.

Interesting concept. Twisted, and I don't think I want my preamp tube in the same faraday cage as my P4, but it is interesting.

Not to forget that the 6c33 makes an outstanding power tube for amplifiers.
