Ralph,
I would agree with you 100% if the reason for swapping the tubes was because of the tubes being microphonic, noisy, suffered from defective construction or were not reliable but I don't believe that is the case here. I believe that Fred just preferred the "Flavor" of the $100 per tube tubes to that of the $19 per tube ones. Perhaps Fred could enlighten us by stating specifically what made the $100 tubes better in his eyes/ears than the $19 tubes? Please let us at the same time know what makes the $2,400.00 Acrolink Mexcel 7N copper power cord better than a $5 stock power cord other than build quality. Please let us know just exactly what it is that this expensive audio jewelry does better than their pedestrian equivalent. I await your answer.
Ralph by the way, I do get what you mean about manufacturers being forced to use mass-produced tubes which leads to the potential to acquire "Better" NOS tubes on the market. The potential is there to get tubes that are less microphonic, quieter, more robustly built and more reliable but it is my view that most tube rollers do not roll for those reasons but for favoring a particular "Flavor" more than other; these is basically trial-and-error "tone control" which is the same practice used in cable swapping and power cord selection.
