Pro's and con's of different tube amps?

Just wondering if some mystery can be explained between different types of tube amps, such as: otl's, set's, push pulls, transformer coupled and others. Also your preference and with which speaker.
The mystery has been explained in dozens of posts over the years, including the relationship between different tube amp topologies and speaker designs.

Search the threads.

I'd suggest reading those authored by "Atmasphere" as being particularly enlightening.
This link leads to an interesting article about SE vs PP.
After reading that link I have to ask ; which PP amps don't sound boring ?

Which SE amps don't act like a furnace and can power a 91db./8ohm speaker with a fairly flat freq. response , minimal crossover network and keep the SE family sound ?

How do OTL's fit in here ?

Thank you .

I'd suggest going to the Atma-sphere Web site and reading Ralph's white papers on the subject of OTLs.

Also, you might find this link interesting that contains some comments from Ralph:
It's certainly good to do some research and get some kind of general grasp of the subject on paper. But your best bet for actually starting to associate sounds or a general sonic signature, with those words on paper, is to start listening to various topologies. The options there are to seek out audiophiles in your area who are willing to have you come for a listen. Go to local dealers. Go to the larger audio shows. Buy and sell used and actually implement the amps you are interested in into your own system, your own room, and with your own music. The latter will require more patience, effort and investment, but will probably be most rewarding. The amp-speaker interface being rather critical makes the latter task all the more challenging (buying one tube amp after another and just sticking in with your existing speakers is probably a waste of time - if you are looking for a tube amp to go with the speakers you already have you may want to start there).

My preferences? Well, first of all, and I hope anyone realizes this, my preferences are not your preferences. Even if you had a thousand audiophiles provide this input and averaged the totals you the results would be utterly meaningless in determining your own preferences. That said, and FWIW, I've loved SET amps for many years combined with horn speakers, but their magic often has a limited range in terms of music that sounds great with them, in my experience. Ralph's OTL amps are great, and much more versatile than SET while sharing some very similar qualities. There have been some PP amps I've enjoyed. Not many SS amps that I've liked over the years, but I've currently found one that has really wowed me enough to own it and sell my SET amps of 6 years. I've also had a pair of class D amps I thought were very enjoyable. If I had to make some sweeping generalization about my own preferences I'd say there have been more things about tube amps that I've liked than transistor amps, but the few SS amps that I have liked are very engaging to listen to. They've been few and far between. I love the seductive quality of SET and for me the colorations don't bother me, and the music I like most is not among that which really challenges the low powered SET amps I had.

It may help in your queries if you try to determine what qualities you enjoy most in a system (linearity? warmth? accuracy? slam? dynamics? soundstaging? etc, etc). Additionally perhaps what kinds of music you prefer (though many would argue that a good amp/system should be able to present all kinds with equally good results). How large is your room. How do you listen mostly?

Hope that helps in some way. YMMV, as always, as far as personal preferences.
same as the pros and cons of ss amps, except they feature tubes.
I sold my Magnepan 3.6s which needed gobs of power to move to high efficiency speakers so that I could try low wattage tube amps. The advise I read on Gon was to start with inexpensive models and move up. That is exactly what I did. I sold my SS amps for $3,600 and started with a $500 tube amp. It lasted a day and it was back up for sale at what I paid for it. When it sold, I was out the shipping cost. Then I moved to the $1,000 - $1,500 range and have never left there. Someday I might but I began tube rolling and am having too much fun to want to move to a higher level amp.

The best advice I got was to jump in and begin trying stuff and then reselling what doesn't work in your system. Start low and move up. Read up but the fun part is getting it in and trying it out.
Thanks for the advise. I agree on the just jump in and listen suggestions.
And luckily I have that available, there are many types of amps I can borrow.
Fortunately I have excellent speakers to audition with and a remarkable source.
