Agree with all you say. But
"At the same time, we are still enjoying a hi-fi renaissance in our little corner of the universe- more vinyl, turntables, tonearms, cartridges, etc. than ever."
No. Not more than ever. in the 50s 60s 70s everyone had a vinyl player and vinyl. But certainly the most since CDs got embedded in the late 80s.
It is strange the biggest growth in vinyl sales is in the 20-30 age bracket, who spend their lives glued to their handphones, yet many want to listen via a near 100 year old technology.
