Matsushita 12AX7 (looks similar to Toshiba) Very clean, sparkling sound, much more present upper midrange, less grand than CBS 7025. Very rich, large, forward midrange, not as bright upper mids as Ei or Silvania.

Less full more resolution than Ei regular 12AX7 or Full music 12AX7, which sounds even more air-infused Sounds about same, considering different age of tubes. Sylvania still has more balance, more inner detail in male (Cohen) and female without sounding whitish. Much more detailed in male voice (Leonard Cohen) than Gold Lion. My preferences are for tubes that are very clear, neutral like good solid state, YET imparting just enough of the even harmonic tube magic without getting muddy.įull Music lots of air but bit more whitish c/w Gold Lion 12AX7, which is less whitish and more focused/solid in upper mids still breathy/wet enough but is bit darker/denser.įull Music likely has more defined slam in bass I’ll share my recent tube-rolling notes in Elekit TU-8600R SET amp.įYI.
