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!

Larryi,
I agree. They certainly make a big difference. I would like to explore the alternatives you mention in the future.
Rebbi,
Sorry, but I had things mixed up. I thought that it was a different 5u4 rectifier that Brian had given you, not a different 6sn7. No wonder that you like it so much. Andy told me that the one that came with the amp was basically bottom of the barrel.

Roxy,
The Psvane 274B (which I just discovered by doing a little online research is a Chinese clone of an old Western electric tube) is not all that expensive, as these things go. I have seen it online for between $100 and $120, at the cheapest. Now, if you want to go for one of the Western Electric originals, those are going for around $1300 a pop. ;-)

Hi, Roxy,
Spoke to Andy at Vintage Tube today and ordered one of those slightly used RCA 6SN7's. I'll let you know the results. Thanks again for the tip!

Reb,
I am really excited for you, and I do mean excited. I forgot to mention that mine was also slightly used, but tested 100% in all parameters. If you don't find it to be a revelation, I will be surprised. Those tubes are old, from the 40's.

The new Dynamo arrived safely yesterday & I got it all set up & out of the box it sounds & looks great. No transformer hum to speak of & no hiss at idle thru the speakers, really quiet all around. Works perfectly w/the volume knob turned all the way up which takes it out of the circuit - running direct w/the internal remote volume control on the CDP. Really a gutsy amp w/immediate sound, good tone, clarity, 3d qualities & imaging - everything we like about tubes. I'm impressed so far & looking forward to breaking it in.
More to discover
