High powered single end 300b recommendations

Wyetech Labs is worth looking into. They have (2) 300 B mono block amps that are superb and produce about 23 watts per channel  running 2 300B tubes per channel.

Aric Audio will build you a very nice PP 300b.   

I'm using an Aric 300B set amp. My speakers are the Harbeth S-HL5+. I'm also using a pair of Rel T/9x subwoofers. My room is 12 x 19 and moderately treated. A Bricasti M3 feeds directly into the amp. My listening distance from the center of the speakers is 8'. I usually listen to Jazz and some basic rock from the 60's- 90's. The volume setting on the Bricastic is usually -20 to -25. This typically yields a volume of 70-80 decibels from my listening position. I have pushed the amp into the 90 decibel range on a rare occasion and not experienced any clipping. I live in Maine if you want to audition my system.

These are awsome but not cheap.
