Single Ended vs. Push Pull Tube Amp - Best amp for you?

Single-ended tube amplifiers are an excellent option for all high-efficiency loudspeakers. They are known for their magical mid-range sound. While the 300B tube seems the most popular choice, there is also the 2A3 Tube that some like better than the 300B one for the sound character. However, 3.5 Watts of power per channel makes the selection of loudspeakers relatively limited. On the other hand, push-pull Tube amps have a very dynamic yet still very rich and colorful sound signature. They can deliver plenty of Watts per channel for most speakers, making it a great choice not only for the less efficient loudspeakers.

So which one do you like best?

Agreed SE is for me, as PushPull cancel out the desirable 2nd order harmonics which give the sound warmth and tonal richness..

Just ordered a KT88 and listening for what I'm in for, yes I've made the right choice for now. But I feel a pair of singles will be on my christmas list. Love your panchance and leaving all the guess work to the viewer.

I liked the SE for the classical strings and the PP for the jazz. Both were great for vocals.

first song sax on 300B sounds deeper and bigger, more comfortable. On female vocals low mids are warmer and wider on 300B, but more clear and prononced on KT88. On electronic KT88 have deeper and better shaped bottom end. Very difficult choice)) I would choose 300B SET as more pure and minimalistic design and leave loud and powerfull musik for transistors))

Excellent vidieo.for the first time i can clearly decern the difference.2a3 more organic.kt88 has element of hardness, edge. Well done. Music ex choice.

Great video. Great sound, 2a3 for me!! More balanced and open. Could listen for hours.. I had 300b push pull mono blocks as main power unit. Once I tested a 2a3 SET there was no way back.

PP KT88 gives more clarity. Some notes/harmonics were missing (suppressed?) from the violin in the Storm (Vivaldi) 10:04”. I recognized the notes because I kept hearing this piece everytime my son practiced to play that piece long time ago with his orchestra group (multi violin players).

KT88. I don't have golden ears, but what I noticed is a much more thin sound on the 2A3. 2A3 has better decay and delicate details (nicer reverb)
I've built a 6B4G SE direct coupled amp and for the added complexity, it isn't any better than my cap-coupled SE el34 and way less power. Just can't justify it.
Honestly, if I build another amp, it will be the humble 6BQ5 SE.

I like the delicacy of the 2a3. Totally worth the power trade off to my taste.

Fezz Audio Mira Ceti 2A3 SE is the winner without any doubt.

KT88 is the most solid state sounding tube.

KT88. More grip on the upper bass and … soft on the voices at the same time. Strange I heard more distortion on the 2a3 a few times on the upper mid range (feminine voice).

Best topology is running say an EL34 push/pull pentode with some negative feed back.

2A3 Lacks control in the base. KT 88 much tighter. Audible at 13:25
