I've been reading these posts thinking that eventually, I'd get a better handle on your question. That's not meant to be a put-down; there are just different ways that I can interpret your question. If I interpret it literally, the answer is easy because when you use the term ""subjective" magic", you're question implies its own answer: everyone will have to decide for themselves. You can't ask for an objective answer to a question with subjective variables.
If I may suggest a question that might serve your purpose and get you a better response, it would be something like: Is there some ineffable quality exclusive to tubes (tube magic)?
Tubes and SS share most audiophile desired virtues to some degree e.g., warmth, soundstage, transparency, detail, dynamics. Each design has it's reputation for providing a mix of those virtues with different relative values. If a designer develops a product with virtues typically associated with the other design, it's called tubelike if it's SS and vice versa. But if there exists an ineffable quality to tubes that some might be sensitive to and others not, that will be the determining factor in the question of whether or not solid state can replace tubes.
