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!

I also learned that as a past, direct sale customer of Reference 3A, I might be able to get a break on the Antique Sound Labs AQ 1005 MARK II DT. Anybody know this amp?
I like having a sub output as an option for a set. That would help open up more possibilities for a SET amp.

One thing I would consider were it me with any tube amp is how hard the tubes are driven which factors into how often they will likely need to be replaced. This can vary quite a bit from amp to amp from what I read.
Reb, I see a $3000 list price on the antique web site yet saw another listing on the web for just over $1000, so based on that limited exposure, I'm wondering how much that unit is really worth? Agon blue book might be an indicator.
By the way, there are also a couple of integrated SET amps from Wright Audio in Oregon, such as this

and this

but I cannot find any real info about them on the web anywhere. Anyone know about these products?
They are good looking amps and very reasonably priced, too.
