I'm with you there. The most annoying noise to me - by far - is power supply hum. If a tube amp keeps that down below audibility, it's a big deal to me. That's so rare. This is especially true when you stack all tube phono stage, preamp and power amps, and drive high-efficiency speakers. That combination is tough to get dead-black quiet, but it's so important.
