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!

In the meantime the Black Treasure 6CA7-Z's are breaking in nicely on the Dynamo. I must reiterate that I can't believe I am listening to a $1,300 amp with no need for preamp. Pavarotti just completed a piece, I'm stunned really; Brownsfan is so right about the bassoon, french horn, and do forth...I'm having so much fun listening to this unit. After the Black Treasure burn in some more I think I will change out the Sylvania 6SL7s for RCA Red Base, then later on change out the Mullard 60s rectfier to the new Gold Lion Brownsfan recommended.

Charles, how is the 378 doing?
I really do love tube rolling and hearing for myself what happens; so much fun. I think this current combo of tubes is going to be hard to beat.
Mikirob,
So, as obviously thrilled as you are with the Dynamo, would you still contend that a directly heated triode like the 300 B would still make a better sounding amplifier?
I'm not being snarky or contentious here – I really am curious.
Because, if 300B really is the way to go, I would even consider building the Bottlehead Paramount mono blocks along with maybe their 300 B based preamp, the Bee Pre.
Rebbi,
I don't take your question as snarky. I would take the 300 DHT every time in a well designed and implemented amp such as the Coincident Franks. I don't know anything about the Bottlehead, except what I have read.

Charles has really outlined what it takes to be a great 300B. The Transformer being paramount along with good design and implementation of the design. I' m not a reviewer or designer/builder. Charles is a better go-to person on this topic.
I commented earlier on the Golden Tube 300B which was a excellent design with very good transformers. It sounded good, but here's the rub, it was poorly executed because of cheap parts, poor parts, poor build internally. Like most SE40, or 300B, they failed and support was basically non-existent. Yet, if you made the parts changes Arthur Salvatore suggested, you ended up with a world class amp, sounding better than most anything out there. Same went for the Golden Tube SE40, which I
also owned. If I were a builder/designer and a design thief with $$$$ I
would build the Lau Brothers Golden Tube amps with appropriate changes ala Arthur Salvatore and some others who upgrade the GT SE40. So, here is an example of good sounding amps gone wrong.

I trust my ears, that is why I keep mentioning the Dynamo. Israel Blume, to
me, has created a beautiful sounding musical amp at an affordable price (you just have to match appropriate efficient speakers of your choice), but it answers your question about "bargain" SET. I'm happy, doesn't mean this is what you want. I just wish the best for you in your choice and that you will be as happy as I am with my choice. I throw out what is going on with the Dynamo to help. Rebbi, sooner or later you'll find what you are looking for. You asked, we answer.

The Mullard 378 rectifier is a superb match in the Frankenstein. This is Noteworthy because the sound is excellent with the stock 5U4G tube. The 378 provides across the board improvement without trade offs .
