300B Tube Amps with 15/16 Watts Per Channel?


Felix Audio makes the dual 300B amp "Lybra"--are there any other manufacturers of that gear?.Does anyone have experience using two each 300B tube amps modified to be two monoblocks with 15/16 watts output power each? If yes, did you hear any difference in the exquisite 300B sound other than more power? All experiences and thoughts appreciated. (Yes, expense is already noted)

@atmasphere said, "Put another way, if your speakers are efficient enough that the SET never needs to make more than about 25% of full power you’ll really start to hear the best of what that amp can do. In case there’s any doubt, this is part of why horns were so common in the 1950s and prior."

How do I know how much power my SET amp is using?

I have a beautiful set of Atmosphere Class D that never give me concern of overdriving them. I also have a Shiny Eyes SET 45 Mesh Tube Amplifier from Radu Tara that I believe is 2 Watts. I use them to drive Charney Audio Companion Excalibur with AER bd-3 drivers (104-106 sens???)

Can I measure (or need to) my output to see if I am staying within the 0.75 Watts to avoid excess distortion?

Thanks and Happy 2025 to all.

As a side, I live in New Orleans and am in ER doc. I worked NYE. I don’t always understand the world, but hope sanity and tolerance prevails in 2025.
