300B or 2A3?

This is one of those questions that just has no single answer. Why? It
depends on numerous variables. Within both amp types there's a wide
range in price, built and sound quality. Then there's a wide range of the
individual output tube itself (a Sophia, EML and Psvane 300b all sound
quite different from each other). Output transformers in either amp are
crucial to the sound. As far as I am concerned either tube type is capable of
truly excellent sound. Some may say that the 2A3 is more pure and has
more clarity and the 300b is richer and has a fuller tone-body. I'm not so
sure as two 300b SET amps can really sound nothing alike. Some 300b
amps are as transparent and clear as mountain spring water. If you want 8
watts from a 2A3 SET if wound have to be a parallel circuit. I think you
could be very satisfied with either amp choice . SET amps are a wise
direction to follow if you want the natural/ realism sound of acoustic
instruments in your home. You speakers can mate well with both of these
tubes.
Charles,

I use both of these amps.

In "general"....I like the very top end of the 2a3 best. I like the 300b midrange better. If I could only have one, it would be a really good 300b.

They will sound more alike than different when compared to transistors, digital amps, even other tubes like tetrodes and pentodes.

With your speakers, I don't think you would go wrong with either of them. I do doubt that the 2a3 you are looking at puts out 8 watts "if" it is truly single ended. Usually it's around 3.5 or 4 watts. As Charles mentioned, it might be a different circuit other than SE but with your AN's 98 db spec and your listening tastes, it may be moot. The difference between 4 and 8 watts is only 3 db.

My guess is you will like both but will prefer the 300b.

Hi Onemug,
To clarify, 8 watts from a 2A3 amplifer would have to be a PSET (Parallel
single ended triode). A single output tube per channel 2A3 is as you said 3-
4 watts. With 98 db sensitive/ 8 ohm speakers for much of the time you're
only using "fractions" of 1 watt at normal listening levels. There
will definitely be advocates for both of these fine DHT tubes as they will
bring your music to life! Like Onemug I'm partial to the 300b SET if built to
a high standard and implemented property. Hueyoz, if I were you I'd try
hear some of these amplifiers. You'll then recognize how they do vary
amongst themselves and sound different even with the same output tubes.
What's your price point? These type of amplifiers cover a very wide
spectrum of cost.
