Yeah, I'm rarely past 11, though IIRC another pair of tubes I have requires a bit more juice with the HE-500s, so I'm not too surprised. Maybe it has something to do with the age of the tubes. I did recently switch from a dying old PC to a slightly more modern laptop, but it's still foobar2000 via USB out to Bifrost to Lyr, so I doubt PC vs. laptop would matter. With the Q701s and SR-225s I rarely approach 10 o'clock. The whole damn unit gets hot, but with the socket savers I can still use the volume knob

"A
getter is a deposit of reactive material that is placed inside a
vacuum
system, for the purpose of completing and maintaining the vacuum."
I recall a discussion about getter vs. getter holder vs. just-use-getter-to-describe-the-shape-cuz-that's-what-everyone-does... @ Audio Asylum. Fun stuff. I'm happy to keep calling the physical piece the getter, as that's accepted parlance.
