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...

Thanks Larry for sharing about the massive OTL amp from Greece. Very interesting!

Whenever I read one of these SET vs. PP threads, I am always left shaking my head. There is just so much more to the sound of an amp than this one aspect. Most of the time people are comparing very different types of amplifiers and they then ascribe the differences to the SET/PP aspect alone. It matters quite a bit what type of tube is involved. Among the directly heated tubes, the 211, 300B, 2A3, 45 and 46 all sound quite different. Then there's the matter of input and driver tubes and circuitry, all of which can sound quite different. The output transformer is very important. Then there's the power supply---solid state vs. tube rectifiers, type of supply filtering, regulated or not, do the directly heated tubes have AC or DC filament supplies? And we are not even scratching the surface of component differences---every capacitor, every resistor, every wire has some effect on the sound. Plus all of these issues apply to both the SE and PP amps.

The bottom line is that amps sound different for many reasons, only one of which is whether they are SE or PP.

In my case, I have 3 pairs of monoblocks, two PP and one SE, and I rotate them in my system every couple weeks depending on my mood. They all sound excellent but in different ways. None is categorically superior to the others.
Hi Sal,
Your listing of the multiple variables involved are true and no one could
argue against that point. But here's the deal, the OP posted this thread
stating a curiosity and interest in SET amplifiers . He's seeking feedback
before making a decision. Presumably he has little or no experience with
SET amps. He has to begin his quest somewhere, so I'd think there's some
appreciation for a dialog about these types of amplifiers and people's
experience with them. Isn't that reasonable? I did the same thing over4
years ago when I developed an interest in the unkown(to me) niche of SET
amplifiers and experienced members here were extremely helpful. I'm
attempting to do the same for Jazz463. Could he be happy with non SET
amps? Of course he could. I just happen to find the SET to be very special
when executed well.

Bombay-as an owner/user of the C&C Abbys, mated with a sub and driven by an EL-34 based p/p amp, I can listen to AC/DC at volumes just short of 'I can't hear the person sitting next to me'.
I'm sure that I believe you.
I was merely asking if the entire system using a SET (not P/P as you are) would deliver for the OP. Something he needs to find out for himself.....
To me it depends on musical taste as well as speaker efficiency as to whether or not an SET will suit your individual needs. I find these amps have their limitations for ALL types of music but fare extremely well with small scale and vocal music. The budget SETs I've personally listened to would be less preferrable than a PP tube amp that would probably achieve greater musical satisfaction over a broader range of music. No one can answer this for you. You have to listen yourself. Like Ralph, I prefer OTLs and secondly a good PP amp for the wide range of music I listen to, but that is me. I would expect a good SET with wide bandwidth performance, convincing bass and dynamic impact would cost considerably more than your budget would allow.

I agree with Bombaywalla, step back, determine what you are trying to achieve within your budget and try to listen to as many options as you can.
When discussing a SET amp I'm speaking of those that are well designed, built and implemented, this along with a well chosen speaker will allow enjoyment of all genres of music.SET is capable of far more than only small scale and vocal (though it does these very well). Lesser amplifiers of any topology(not just SET) will lack this ability. In the stated price range I'd agree there are more choices among PP amplifiers. Good quality SETs don't come cheap but can be found for reasonable cost. Any amplifier type has 'some' degree of intrinsic compromise along the performance spectrum.
