Would You Rather Own A Good SET Amp, Or A Great Push Pull Amp?

@hwr stated " I've been the proud owner of a pair of Klipschorns for the past 48 years, " 

Hats Off to You , being dedicated to a particular End Sound and the knowing of how it is capable of impressing is a very good place to be.

My ESL 57's both as Single Height and Stacked Array share similarities in their age with you own Speakers and a Pair are with me since the 90's.

They have been used on a variety of Valve Amp's and I have also heard the same model on a extended range of Amp's in PP - SET - OTL - SS.

I am always left impressed.

Are Vintage ESL's the best Speaker, certainly not, I have other Speakers that are parity in their attraction and leave very good impression as an End Sound.

Vintage ESL's and Valves have been part of my audio interest for more than half of my adult life, they have a place that is permanent as long as I am with health and hearing.  

I am a converted SET user, I failed to Wed to them at another time in life and very recently have found it difficult to consider anything else to listen to, but the 300b SET recently brought into the home system.

Helping out a Widower with my becoming a buyer of a few of the deceased Spouses audio devices has certainly been a game changer in my little world of audio, in both Amp' Design and Speaker Design. 

Hello, this is an interesting discussion that is relevant to solid state designs too, of course. Speaking of that, and  bringing this discussion down to the level of physics and transmission of sound waves through air, what about this assertion from Nelson Pass:

https://www.passlabs.com/technical_article/single-ended-class-a/

Virtually all the amplifiers on the market are based on a push-pull symmetry model. The push-pull symmetry topology has no particular basis in nature. Is it valid to use air’s characteristic as a model for designing an amplifier? If you accept that all processing leaves its signature on the music, the answer is yes.

Enjoyed reading this thread.  Educational, many different points of view, civil discussion so lacking in other threads these days.  Well done!

The Pass read very interesting, never heard the analogy to air argument previously. .

My earliest references for audiophile sound quality was Audio Research with Maggies and Dahlquist DQ10, this and the Dynaco ST35 with Dynaco A25 at the other end of things. Being a complete novice, I'd listen and half believe the crap Stereo Review mag threw out, as did much of the audio audience. Problem was going through all this great measuring class a/b amps I never came close to achieving sound quality I heard with my references. Over time I migrated to my first class a ss amp, N.E.W. DCA66, this battery power, resembled Pass designs. Finally getting closer to my references, still no cigar. From here I finally decided to take the plunge back into tubes, Conrad Johnson MV55, sweet, golden glow tube sound, loved that romantic presentation for a few years, what vocals! And then we go on and on over the years with a variety of push pulls looking for something between the romance and the analytical. Fairly successful, and then I get the horns and SET, took some years to get it all exactly to my liking, never thought I'd go back to push pull, and then this new Bendix 6094 mono blocks, now reconsidering push pull although this will never wholly replace SET, will always maintain a 300B amongst the collection. Now considering adding a Type 50 tube SET to collection. A First Watt always a lure as well. I'm always mindful every watt counts and should be highest quality, far more difficult to produce vast number of quality watts vs a single or just a few. 12wpc may be my max.

I do love to romanticize about a sweet 300B, 2A3, or 845 amp, and I keep saying I'll end up with one.....but we'll see. I love my Aric Audio "Push Pull" EL34 amp, and will die with it.

For years I've have a Bob Latino Tubes4hifi ST-120 amp that can run in "triode" or "ultralinear" mode. It's a $2,000 amp including tubes, and I just don't give it enough credit; it's a little brilliant amp. It responds really really well to tube rolling too.
