[Elecraft] Drake twins quiet compatred to K2?

I dunno about how much quieter tube radios are, but I've heard the same
description as to why tube rigs sound better (even vs odd order harmonics).
The golden glow reflected on the wall doesn't hurt either ;).

Whatever the reason, I do know my ol BA Hammarlund HQ-180 sure sounds sweet
listening to DX AM late at night.
