I would agree -- tube amps have their place and are nice to have. Not just tube amps though. The Pearce G2r combo SS amp is killer.
Regarding turntables and vinyl -- I'd be interested in the demographics of who's buying those. If I had to guess, it would be the baby boomer crowd with a huge dose of nostalgia -- not the millenials.
The 1 million figure comes from a recent annual report of the German phono industry association, the 2-figure percentage also (as well as magazine articles). I am following this subject with interest for quite some time.
Even large record stores stock up their vinyl offer every year, it is not only the small specialist record shop anymore that supports vinyl records ... and this is not predominantly electronic music anymore either.
Almost every "important" album (sic) release in these days is also being released as a vinyl record. This would have been unimaginable 5,6 years ago.
Actually a large percentage of vinyl buyers are people in their twenties and thirties, so not really the baby boomers (who actually show a declining interest in vinyl).
The Audio-CD is dead.
Try to get a decent CD-player in your electronic chain store these days. It is almost impossible. You can rather go to a thoroughbred HiFi shop to buy one.
Philips has stopped developing CD-drives (which also affects audiophile manufacturers who relied on their drives for their own products).
So it is either audio files or vinyl in the near future.
The 192 kHz technology however is an interesting trend to keep an eye on in regards of digital music.
