Mr. Raul, I am left confused by your comments. I know little about the physics of tube and solid state devices, but does not current run through every component within a piece of equipment? And if so, does not each component, whether it be a capacitor, transformer or electron tube not have it's own signature? And if not, does every solid state, by virtue of it's being solid state, sound identical and therefore, equally accurate?
I have enjoyed both solid state and tube equipment with each giving a facsimile of recorded instruments or voices, but never have I heard a system reproduce the live sound I experience when attending a live performance. Solid state may offer a so-called quicker, more accurate, less colored interpretation, but seldom have I heard it carry the body and weight that has accompanied some excellent tube components. In my experience the best of tubes display a huge soundstage, a rounder and fuller image, and a most life-like decay. Bells and string instruments can have a body much closer to the real thing. I do not intend to prescribe one philosophy over the other, since I find both a distance from the real thing.
Incidently, I have heard some solid state amp designs with a softer more tube-like presentation, and contrarily tube systems sound hard and edgy. So much of this may depend on system synergy and specific tastes. I am usually not fond of analogies, but when viewing an artist's portrait, it may never carry the accuracy of a photograph, and yet it often offers something more approachable. Trust your ears. This is not relegated to a mere science.
