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!

Okay,
I want to thank everybody on this thread for all the valuable information. I think I've got it narrowed down to either the Coincident Dynamo or the Decware SE34I.4, which are similarly priced.
Everyone's enthusiasm for the Dynamo here is very impressive, but I think there are 3 hesitations I'd have on the Dynamo.
First, I wonder if that volume knob nestled between the two tubes up front is a finger-toasting hazard.
Second, I am a little bummed that it has only one input... that just means that I'd have to unhook my DAC and hook up my phono preamp whenever I wanted to listen to my analogue front end. Not a deal breaker but kind of a shame.
Finally, I'm a little put off by the consensus that the amp doesn't sound its best with the stock tubes, but requires tube rolling (and additional investment) to sound its best. On the other hand, I take it that the amp's built to a certain price point and that this dictated some skimping on tube quality.
Your thoughts? And thanks for all your help I really do appreciate it.
By the way, I called Coincident today and believe I must've have spoken to Israel Blume himself. He was very cordial.
Rebbi,
Just about every tube component regardless of its cost will improve with tube experimentation. I find this to be a plus. It's not that stock tubes sound "bad" but that there's room for such pleasing advancement, a bonus IMO.
Charles,
Rebbi, I'd be willing to bet the stock tube issue just build down to individual preferences and synergies with their stuff in their specific cases. When different tubes sound different, the maker has to decide which to provide. They can't provide them all.

The one input issue is a factor but there are workarounds for that, using an eternal switching device for example.

The volume knob location may or may not be a real issue. Existing owners could probably say best.

Its a fine looking product, but no single product can meet everyones needs best. Features, aesthetics, etc. matter too in addition to sound quality, and are often the deciding factor.
Tube rolling is fun and can really improve things.
But, increasingly, not a road to go down without a fat wallet.
Rebbi,
You do not need to roll the tubes, it sounds really great stock. You misunderstood the discussion. I enjoy rolling tubes to tweak the sound to my preferences. In fact, as it turns out, I believe I now prefer the sound of the stock Shuguang EL34B slightly better than the NOS RFT Siemens I recently purchased at a cost of $200 for the Dynamo based on Tim Smith's 6 Moons review. If you read Tim's review he used the Siemens, SED Winged C, Psvane Black Treasure, as well as the stock tube; he settled on the Siemens. That of course was to his ears in his space, with his ancillary equipment. In my space with my ears and my ancillary equipment, I think now after listening that the stock tube (again, my space) sounds more open, airy, better separation between instruments, easier to discern what is where, provides a bigger, stage. The RFT Siemens is a bit richer and warmer still, deeper bass, yet not better, just different. Both tubes exhibit wonderful tone, excellent harmonics, dynamics, stage and so forth. The Dynamo will play everything you throw at it in a natural and organic way, it is a musical amp, neither too Yin or Yang, but just right. I have a matched pair of Black Treasure 6CA7s on the way from Grant Fidelity, but you don't have to do what I am doing, comparing and contrasting tubes. The Dynamo sounds great as is.

To answer your other question the volume control is not a problem for me, likely not for you. I'm only going to play CDs on this amp, so no problem with additional inputs.
