Everybody has their favorites; Everyone claims to have the "best";etc.etc. blah,blah,blau...
I've heard tube systems that sound real and I've heard tube systems that sound like toobs;
I've heard solid state systems that sound real and I've heard solid state systems that sound like transistor radios only louder;
I don't hear in digital, but maybe some do.
I'm for what sounds real and believable- whatever the technology. Maybe that's why so many are using a combination of technologies- tubes and solid state in the same system- or even within the same component.
In the end- it's all about low noise, good harmonic structure- and distortion levels that are below our ability to perceive as un-natural.
There is, after all, some distortion in real music.
