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?
Thanks!

Got my new driver board for my AN Kit 1 from Digital Pete in Florida. Got the old board removed and hoping to get the new one installed in a day or two.
I'll report back!
Joining the DHT SET amp world next week with a unique 845 amplifier designed by Larry Moore of UltraFi. His Monaco 845 design. The 845 tube is not pushed to its max and thus the amp put outs 10 watts, not the typical 20-28 watts per channel. DHT 45 tube drives the DHT 845. The amp is massive weighting in at just over 80 pounds or so.

Five separate power supplies! Yes, I said 5! I'll report back next week on the sound & synergy.
Correction. 6sn7 feeding 46 feeding 845. The power tranny weights 35 pounds by itself! The design brings the very best qualities out of these 845 tubes by running them at their sweet spot tonally.
