push pull or single ended

First post here and appreciate any replies.  While not new to high end audio, I've never had a tube amp.  Looking to purchase a new amp for my mid/tweeter cabinets in a bi-amped system.  Thinking about a tube amp as I've never had one and have read a lot about them, mostly all positive.  Never having heard a tube amp, I'm wondering if I'd be able to hear a difference between the push-pull type and the single ended type.  Not a huge budget as I'm on a fixed budget.  (63yrs. old and on disability for 20+yrs.)  Appears I could get more watts per dollar with a push-pull amp but don't need a whole lot of watts as this is for the top end of my system.  Also like to get a new SS amp for my bottom end but that's another subject.  Would I be able to hear a difference between the two types of amps?  Thanks for the input.  BTW, not really anywhere I can audition the two types.

A push-pull amp is an easier transition from a SS amp. Set amps are a different animal.

An easy recommendation are the Dennis Had (Cary) Inspire Audio SE 6L6, EL34, 6550 and KT88 amps. About $1300.

Nelson Pass First Watt F2 class A SS amps are also a good choice.

Nice idea, I agree, go Push Pull.

Your efficient speakers means you can easily stay in the 25-30-35 wpc power range. That gives you lots of options, lots of competition there.

new, used, vintage.

Having return options is a great means to success.

As mentioned: less power = less weight; less heat; more placement options.

.........................................

some things to be aware of while searching:

a. Some new tube amps, like my Cayin offer two modes of operation: i.e. 22 wpc in Triode Mode or 45 wpc in ultra-linear mode. Not needed, just mentioning it. I and all my friends prefer the more common ultra-linear mode. It’s not really the additional power (especially with efficient speakers), the sound is different, some like Triode for certain types of music and Ultra-Linear for other music.

b. You will discover ’tube rolling’. i.e. my amp can use either 6550 power tubes or KT88 tubes. It came with 6550’s, very nice. After a while, I tried KT88’s. I prefer the KT88’s. The bias for KT88’s is different that for 6550’s, that is a good reason to have easy external bias control.

c. Many tube amps offer easy external Bias control, with external adjusters and meters, I wish my amp had that.
