Physics limits the 300b SET to about 8 watts.
Switching to tubes often means you need to switch speakers.

High powered single end 300b recommendations
I would like to try a se 300b integrated to find out what the famed sound is like. However, at 86db, my Harbeth S-HL5 are not very efficient. They need more like 25-30W to drive them.
Any recommendations on an 300b amp that will work with these speakers?
