Well, since others have braved this volatile subject, I'll stick my head out. The difficulty with your question is the "Which one is better for excellent sound?" part. The problem is that "better" is subjective not objective. Had you asked which one is more accurate, the answer would have been easy.
But, as Ken pointed out, many prefer the "less accurate" choice. Since that preference is subjective, those who do ought not be berated for that preference. Unfortunately, we are unable to tell you which
you would consider to be "better."
Unlike Ken, I have heard tubes, but it's been about 40 or 50 years, and everything back then was tubes
. Shoot, I can't remember what I had for breakfast let alone what tubes sounded like half a century ago. (OOPS! Just remembered I haven't
had breakfast yet
). But, like Ken, I'm a "multichannel" guy now, so my preference is obvious and my choice easy.
