hello Roland! you wrote: 1. "If a tube amp has sufficiently low out put impedance " if!!!! it's not always. it's depend of scheme, solution. we have to reach it first. the same as transistor amplifier. 2. "and not necessarily the low power output" - it's depend of drivers sound pressure. if you'll load any amp to driver 0.08 Pa - high damping factor of your amplifier don't take a big sound. but 0.4 Pa driver be able to makes biiiigggg loud! :) by 1W a propos, what do we mean about 1W to 4 ohm? U^2/R. ok. U=2V. nice. signal swing have to be about 5V by oscillograph, couse it's mean square value. sorry my English.
