You are asking the wrong question. What tubes offer that SS cannot compete with is space. You hear a soundstage where vocals and instruments have their own space. While this is a generalization, that is the difference between many reference level comparisons. While some like the 6H30 tube sound, to me it sounds SSish so in my experience, then just get a SS components. The real question is what are you looking for from your system and in what price range.
Once you know what you are looking for then you need to audition them. Take your time and enjoy the search.
Happy Listening.
