I'm about 150 hours into the new tubes and they're an unbelievable improvement-very stark improvement in top and bottom, and everywhere in between, really. I have each monoblock hooked up to a PS Audio P10-just FYI the current draw is actually less than it was when i was running 120s. Still a work in progress here but no problems.
