What is your price range for a SET amp?
I don't think you are going to find many SET amps that do well with 4 ohm/86dB speakers at any price range except the $5k and up. Even then, that's not a SET strong point.
Unless you listen to a lot of folk, a cappella, chamber music, etc. Still, it would probably take one of the high power SETs to make things work.
If you want tubes that will work well, look at push-pull designs.
