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)

I built a parallel 300B SET based on an ANK kit with a lot of modifications. I don’t have much experience with a single tube SET, but my amps sound very nice. Check out my virtual system.

You could also do a pushpull 300B amp that will get you closer to 25 watts.

If you don't mind assembling a kit, Bottlehead makes a 300B model called the Kaiju that can be configured to work as a 16W monoblock amp. I have the Kaiju configured in stereo mode and am very pleased with its sound quality. I can only imagine that the Kaiju in monoblock form would sound just as good or better, but with more power. Bottlehead kits are very complete with superb instructions, which makes for a relatively easy build.
