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...

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.
Hi Charles

Yes I am sure you are talking about those that are well designed as was Salectric, at least that can perform at a satisfactory performance level that they can be used on a wide variety of music. The output transformer and power supply design would certainly come into play as it does with all designs but more so with an SET to realize realistic performance across the frequency spectrum. I have yet to hear a budget SET, admittedly the breed I'm most familiar with, perform adequately full bandwidth, at least from my perspective. This isn't to say they don't exist but I doubt at the budget the OP is looking at. This is why I chimed in on this thread. I personally feel that a PP or say a used Atmas-phere 30 watt stereo OTL may be a better alternative unless he listens primarily to small scale, music where a budget SET would be satisfactory and perform quite well, that magical midrange. I have heard a few expensive, well designed SETs that were superb across the board, the Lamm being a great example with the Russian 6C33 tube, not typical for sure and very expensive.

Since their reemergence as a more mainstream audiophile alternative for high efficiency speakers 20 years or so ago, there have been numerous offerings at various pricepoints so I'm sure there are some that offer excellent performance for all types of music. Out of general curiosity I too would be interested in hearing your input as to what one might have to spend to achieve what I have described above and a few examples.
