Tubos y su firma sonica

Hola

He estado buscando información en la red sobre las características sonicas que entregan diferentes configuraciones de amplificadores con tubos. No ha sido fácil... para variar, en este tema tampoco existe mucho consenso y también se da para disputas entre rojos y azules. Entre lo mas rescatable que encontré, esta este resumen, con la valvula vista en configuración SET y PP. Bienvenidos sus comentarios y experiencias.

EL34
SET - Sweet midrange, airy highs, a little rolled off bass, slow dynamics, fair imaging but high voices blurred in soundstage
PP - Has bass punch lacking in SET but grainy midrange and dull highs, tight soundstage and good PRAT

KT88
SET - Plenty of bass punch, sweet midrange, clinical and cold highs, tight imaging, good dynamics, jumpy
PP - Loads of bass, somewhat scooped out midrange, outstanding dynamics, slightly blurry imaging, tizzy highs

300B
SET - clean and clear, outstanding resolution and imaging, excellent frequency balance, tight but unassuming bass, wide variation depending on manufacture. WE tend to be the best, new JJ are pretty good, the oversize "320XL" etc are very good also.
PP - good dynamics, powerful sounding, a little more veiled than SET 300B, produces a somewhat collapsed soundstage. clear neutral highs, unremarkable midrange

2A3
SET - clear and sweet at the same time, excellent soundstage, a little light on bass but honest at reasonable volumes, good frequency balance in mids and above, airy highs and clear mids. A little flowery in overall presentation.
PP - a lot like SE 2A3 but makes up for the lacking bass power of 2A3 SE. Soundstage a little collapsed as in 300B PP

805
SET - Painterly rendition of sound, like a Seurat or Van Gogh, very beautiful but certainly not neutral, yet authoritative at the same time, good bass punch and good balance of frequencies overall.
PP - very powerful and neutral sounding and somewhat etched, as is viewing a bas-relief. Highs are in your face but may be just the thing for vintage AR speakers

845
SET - Everest-like headroom in presentation, precise soundstage, and well-balanced frequencies. Harmonic structure similar to 300B and 2A3, but even more neutral.
PP - Effortless sounding, highly liquid and yet commanding in tone. lack of even harmonics to the point of being transistor-ey. a little over-emphasis on the mid-bass but could be great for woofer or a sub.

El comentario de la el 34 no es para nada cierto eso depende de la polarización del tubo
El tubo el34 es uno de los tubos mas rápidos y precisos que hay la imagen y microdinamica que logra es envidiada por otros tubos
Además no sufre de feedback electroestático y uno puede jugar a voluntad con eso para sacarle un mayor rendimiento a nuestro diseño
Este fin de semana estuve escuchando un prototipo bien interesante denominado single ended súper pentodo
Y saca rendimientos superiores ...

tambien falta informar que si el sonido experimentado es con tubos nuevos o NOS, o rusos, chinos y etc :lol: ya que ahi tambien hay muchas diferencias/influencias en la calidad del sonido :blink:
