Can they be significantly more efficient than these?

I like the "Infrared Coating", whatever that is supposed to do...  ;D

Well, actually it's not totally stupid. It's described as a surface treatment that helps conveying heat from the tube to the crown. So I guess it's just some kind of matte black finish. Now, does it compensates the reduced convection effect?...

Outside?  ;)

"For a guaranteed upgrade, mount up our $36 Tube Crown andyou’ll hear a major increase in musical warmth, transparency and detail—plus deeper, cleaner bass and extra treble air."

Shouldn't that be deeper cleaner brass?
