What's the greatest bargain in SET these days?

Hi, Gang,
I response to my recent review of the Reference 3A De Capo BE speaker, someone wrote that if you really want to hear them sing, you should try them with a SET amp, or words to that effect.
That got me thinking. The De Capo's are 92 db efficient, which (correct me if I'm wrong) seems kind of borderline for low-power SET amps.
In any event, right now I'm running mine with a pair of Manley Mahi mono-blocks. They are switchable from triode (20 watts) to "ultra linear" (40 watts). I run them in triode all the time, and in my room, the volume knob almost never goes past 9 o'clock; more would just be too loud.
All that said, what do you guys think of running the De Capo's with a SET amp? And if I did, what's the best bargain in SET's these days?
Saki, Will do. Be patient, the dynamo is for a bedroom system for which I have not yet bought a source. However, I think I will leave it downstairs and use it for background music during the day while I am working around the house so I can get some hours on it. It is shockingly good for the money. I really want to see what some hours and a better tube complement brings.

Brownsfan, one might get the impression you like this amplifier, LOL.
Would it be fair to call it a Frankenstein jr? Or son of Frankenstein?
