" Tubes have varying degrees of coloration as do transistor components. It just depends on what type of sound you are seeking. "
Not only that, but you can make the case that SS has a much wider range in "type" or "coloration" of sound than tubes. Consider SS power amps or preamps from these companies: Pass, Ayre, Levinson, Spectral, BAT, Rowland, ARC. SS products from any of these companies sound completely different from each other. I can't think of any brands of tube products that have as much diversity as the companies I listed. And that was just off the top my head. I'm sure we can come up with a lot more examples to add to the list. The point is, with such a diverse selection of sound, I see no reason why SS should be considered "better", or more "accurate" than tubes. If that was true, they woudldn't sound so different.
