Gilgamesh 242 Publicado Enero 13, 2013 Share Publicado Enero 13, 2013 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.
