Classic el34 tube amps versus current models

The top line Jolida line has many upgraded capacitors,resistors and  in amplifiers 
the transformers,power supplies are the heart of any quality power amp, or integrated . And these 3502 with specific letter I forgot retail $2300 for ,el-34, 60wpc.
and 80wpc with the kt150 tube which is very dynamic but still has the soul of  most a el-34 tube but with added punch.

Meiatflask, 
It can become somewhat complex when comparing different types of amplifiers due to the multiple variables involved. Yet at times one can make general statements that have merit based on observation and experience, they just aren’t absolute proclamations.

I’d prefer the 300b even as a push pull over an el 34 simply because I believe that it is Intrinsically the better sounding tube. There is a used Audio Space Reference 3.1 for sale on Audiogon that is a 20 watt push pull 300b amplifier for 3 K USD. I say this amplifier with appropriate speakers will provide enormous musical joy.

I still have my ST 70 as well as PL 7 monos. Over the years, I've own several more modern el 34 based designs as well. The Dyna generally has a bit looser, fatter bottom end than the others.   Beyond that, I'd say that characterizing sonic differences between any of these amps is almost entirely dependent on the speaker match.

Hello Meiatflask,
I would agree with charles1dad that SET amps generally do all the things you said you want better than EL34 amps. Line Magnetic is getting amazing reviews for their amps, and there's one based on the 845 tube for sale within your budget here: http://www.usaudiomart.com/details/649217914-mint-line-magnetic-518ia-set-tube-amp-845-one-owner-gol...

However, if you really want to stay with the EL34, and get the best of the classic sound without its weaknesses, I would second whoever above recommended the Music Reference RM9. I've seen a couple listed on A'gon within your price. I used to own one so I can attest to their musicality. Nevertheless, any true triode amp will outperform it. Just my opinion, of courses, and it goes without saying that YMMV.

A used Line Magnetic 845 SET or the Audio Space Reference 3.1 300b push pull I pointed out yesterday, either would be wonderful choices for 3 K USD. No question about it. True high quality amplifiers.
