45 Type Push/Pull

Nice post Larryi, no single amp topology does it all.SET is`nt perfect across the board(what is?) but their natural presentation and non mechanical sound is more emotionally real and involving IMO.

Gsm18439(Gary) you`re right, it`s difficult to generalize 300b sound. Depending on the brand they vary from soft,slow and rolled off to simply brilliant sound(Takatsuki-TA) and all stops between these extremes. There are many flavors of 300b tubes.Of course the quality of the individual amplifier is another 'huge' variable.

Just remembered that I have heard the VAC Renaissance amplifiers which are DHT push pull.It's been quite a while but I really liked what I heard from them.

Larryi,
I find with a good SET amplifier I can expand the usable volume range in
either direction. At medium and lower levels they maintain a healthy sense
of pace, flow, dynamic contrast and remain very musically involving.The
transparency, tone realism and full body preservation seem responsible for
this. Conversely I can listen to complex music at high sound levels and
everything remains clear and very articulate, it all stays connected and
holds together well. Probably the big advantage for me is they avoid the
dreaded over emphasis on transients and the artificial edge and sharpness
it brings.You get the natural attack yet preserve the decay and the sustain
that I find vital for realism and avoids that hifi mechanical presentation I
often hear with other types of amplifiers.Larry, I agree it'near remarkable
the difference the brand or quality of a tube or amplifier can make within a
certain genre.

Larryi,I agree, certain large scale music if loud enough can push a SET to its limit. No amplifier is best at everything, some amps are better for the example you gave but then those amps would fall short elsewhere. The Takatsui-TA 300b is superb and I much preferred it compared to a re-issue WE 300b in my amplifier(the 'vintage' WE 300b is just too costly).The Sophia Royal Princess is excellent in my amp(close to the Takatsuki in sound quality). I just ordered a pair of the EML mesh plate 300b(a true woven metal mesh tube). I `ve been very curious to hear what this tube is capable of compared to the Takasuki. The EML has developed a quite a reputation for good sound and reliability.

Agree,implementation of a product is crucial to the actual performance
level. I'd also prefer a well design and built PP amp over an average SET
amp . However if both are done at a high quality level then give me The
SET.I find the level of involvement and emotional connection with music is
for me unmatched.I react to them in a very spontaneous way, head
nodding, foot tapping, humming, imaginary playing along with the
musicians etc.They provoke a lot of goose bump moments and completely
satisfying immersion into the soul of music. These are attributes that can't
be measured yet are so powerful when present.Other amplifier
types can do this(to various degrees) ,but in my experience not nearly as
often nor as deeply
felt.SET amplifiers won't be the answer for everyone but they are ideal for
me.I haven't any experience with the DHT push pull amps, just the pentode
tube types (I like them wired triode rather than ultra linear).I wonder how
much I like is actually due to the DHT tube genre itself.They seem more
musically natural and present more realism then IDHT tubes (well to me
anyway).

You raise an interesting point, the quality of the output transformer and power supply are so critical to what you'll hear with a SET.Get those done to a high standard and sit back and enjoy. Compromise with those aspects and you will never know the full potential of this type of amplifier. It's true for all topologies but seems more so for the SET.
