The idea of buying a "vetted" tube at a much higher price is an interesting concept. IMHO, who ever thought of it was a very smart marketing person. The question is....how much validity is there to this approach for the a'phile consumer?
The other question that comes to mind, is how many non-"vetted" tubes can one buy for the same price as the "vetted" tube? Something to maybe ponder, LOL.
