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!

Digital3:

Decware Super Zen? Really? 2 Watts into an 8 ohm, 92 db speaker like the De Capo?

You think so?...
Speavler, Thanks for the comments. The 6SN7 I used was a Class A Sophia, vs a cheapo $15 6SL7. Please let me know how the KT88s work out for you. If one could address the soft muddy bottom end, this could be a pretty nice amp. I really liked what I heard north of the mid bass. It did work a little better with my 94dB efficient Triumphs, but not nearly good enough. I'd like to hand on the the inspire if I can make it sing.

I don't think so Brownsfan, at least not in my room with my speakers, it didn't even come close to being a pretty nice amp. I really wanted to like it too, mainly due to it's ability to play with different tubes. Mine was the KT88 version and came with a pair of Gold Lions. I also tried 6V6's. I used 6SN7 and 6SL7's and had slightly better results with the 6SL7's. The soft, muddy bottom end and rolled off high's weren't the only problems with my speakers though (91 dB, 8 ohm). The soundstage was the size of a postage stamp, I never heard my system sound so constricted. Dennis was sure the amp was damaged in shipping, so I sent it back for him to test, nope, not broken.

I really loved working with Dennis, his energy is contagious! He worked with me on custom colors and tubes, but I just could not get that little amp to open up and sing. He refunded my money, so in the end it was a fun experiment, but just wasn't meant to be, for me anyway.

As for KT88's Dennis seemed to like the Northern Electric version, but I wasn't going to spring for $180 per tube unless the sound had more potential to start with.
Tube rolling can result in sound performance improvements but won't make up for inadequate transformers and power supplies. I believe that this accounts for the big difference between the Dynamo and Dennis Had amplifiers. Brownsfan, does the Dynamo feel heavier or more substantial?
