Tried this briefly tonight. I seem to prefer Ultralinear than Triode. Tried it on vocals and large orchestra. Seems that, for me, mas makapal ang tunog ng ultralinear. Do I make sense?
I'm not an audiophile so can't really express what I hear in the correct words.
of course you do....that is you....
i always tell people, i can explain the technical details but in the end
it is all up to you, i can not tell you how to enjoy your music...
let me try to give you an insight as to why you found ultralinear more
to your liking....for one it has more power and so can provide more spl...it has a local feedback to the screen grids that lowers plate resistance to make it mimic a triode.....
pentodes are much easier to drive than triodes,
voltage swing to a pentode grid is much smaller than for a triode...
so that when you switch from an ultraliner to a triode,
there is a shift in operating points, and it is not optimal
for a triode, surely it will work nevertheless...
a triode is a like a thevenin source, a pentode a norton source...
in the future, i hope you can get to listen to a pure pentode amp
and that will add another dimension to your experience...
