SET amps ?


Hi all, I have been a budget system builder since the mid 70's.I still have my first system ( Marantz 1060/Pioneer PL 12D ,JBL l36.I stopped in the mid 80"s for kids.I have Adcoms,NADs several Marantz's you know the deal.Anyway I picked up a pair of Tekton 4.1's and have them powered by an NAD 314.The question is , is now the time to try a SET tube amp ? I have been looking at several in the $750.00 to $1500.00 range. I do have a nice small listening room for the 4.1's . The Dared MP 2A3c looks interesting at the price.Any feed back would be helpful.How long do the tubes tend to last ? Thanks...

When someone is determined and able to try something new and different, there is no time better the present.

Dared seems like good value. I think of TEkton in general, monitors in particular, as pretty set friendly, but not I am not familiar with those Tektons specifically.

I would expect very nice results with a Dared/Tekton pairing for very modest cost.
I have no problem with any kind of music selection as far as SET amps are concerned. If they are paired with suitable speakers, they can deliver clarity, detail, weight, and do everything quite well. But, they are considerably harder to match with speakers, given their low output and quite high output impedance than a pushpull amp, and probably harder than an OTL given how low the output of most SETs (an issue for me because I prefer the 45 and 2a3 tube over 300b or 211 or 845). But, I also agree that most of the lower priced models do not deliver the goods--it really does take high quality output transformers to get decent SET sound and that does not come cheap. I've heard a few of the supposed giant killers and the sound of these tend to be quite bad--anemic, dead and too light weight-- in the setups I heard (perhaps the amps would have sounded better with easier loads).

OTLs are no different from other amps--each implementation/tube type sounds different. Atmasphere and Joule OTLs, for example, sound very different and which is "better" is a matter of taste.
I agree that Jazzman463 has left the building!! ;-)
But it is clear now from the discussion that Charles1dad, Tubegroover & Larryi have been having that with Jazzman463 having only $750-1500 available that he should not bother looking into SETs. The quality in the power supply & the transformers is simply not going to be there to deliver the goods. Better options might be Atma-sphere 30W/ch or a P-P like the RM10. thanks.
I'm absolutely enthralled with my 2 watt Decware SE84 SET amp. After having been through a few solid state amps, some considerably more expensive, and another single ended pentode design, it's the SET that ticks my boxes.

The resolution, imaging and musicality of this one are just heads and tails above everything else I've had in my system.

At just under $900.00 I think it's worth a try if you've got speakers that are efficient. It's a 2A3 design with point to point wiring and high quality custom transformers. The primary compromise in design is the aesthetics, not the parts. The SE84 amp will not win any beauty contests though, that's for sure.

While big orchestral or heavy metal music won't sound good on my system, I suspect it's more due to my speakers than the amp. I really believe that with the right speakers, this amp could do just fine with complex music.
Bombywalla,
Yes the OP has apparently moved on. However I've enjoyed the contributions from you, Larryi, Tubegroover and all the others who've contributed interesting posts.
Goldeneraguy, I imagine your Dehavilland 845 SET and Horning speaker combo sounds fabulous!
Charles,
