Thanks for the link, it was a good read. Some of the comments are savage, but a few solid points are made in them.

A very cool read and especially cool pretty sure I was at that Willie Nelson show with Allison Krauss opening, it was at the Greek Theatre in Berkeley 7/23/15 the timing is right, the author says he's in the Bay area and it's a hillside amphitheater. 
Well I can vouch for the accuracy of Grateful Dead statistics mentioned in the article!

It’s rather apropos that the article mentions "If it measures good and sounds bad, it is bad. If it measures bad and sounds good, you’ve measured the wrong thing” and "people are too fixated on the gear and not enough on the experience the gear is supposed to provide".

That is essentially what I’ve stated in other threads throughout this forum, albeit worded a bit differently.

To me, here are the take away’s (either mentioned in the article directly or gleaned) as justification to avoid tubes in favor of solid state. To be fair and to avoid drawing the ire of the many tube lovers, designers, etc. on this forum I understand the point of using tubes - succinctly and presumably, more accurate sound reproduction as compared to SS. Tubes:

- expensive (for the highest of quality)

- variable quality (even within same brand/model)

- unpredictable longevity (can last for many years but requires "testing" every so often and typically may last only a few years; hard to tell if tube itself is operating at its potential peak performance)

- fragile (generates and inordinate amount of heat, capable of amplifying something that comes into contact with it, can break if not handled delicately, etc.)

- finicky (more difficult to integrate properly with all other components, less forgiving )
