Hi!
Unfortunately mee too, I'm not able to recognize all speakers and sources at first sight
I havn't done research about big amp tube, and unfortunately I can't remember the label on glass, but imho they are normal tube

They played every kind of music, not only audiophile records, jazz and blues as usual. Old rock, as usual every room played also tracks cd of visitors, that increases the variety.
Reel to reel was only a short stall with service for tapes (maybe translation of music?), sale and repair. There are still alive a niche of people that still uses this kind of equipment but in normal show, I've seen many notebook as source, cdplayer and vinil
You're right, there was many good turntable.
One thing I noticed is that the aesthetic component of parts it's raised to its maximum. Design, good looking parts, but most often a beautiful shell...

My favourite...
1th place: Acapella Plasma unit, imho the bigwig, It sounds different from all the rest. I saw that flame was really tiny, purple-red flame (but horn is in polished brass, for sure that material gives a good warm color than cold aluminum), size in idle condition, as far I could see, is 5mm, no smell of ozone at all. Complete speaker in show is called Atlas, maybe 85k $ priced, due to small and ugly room, the bass and mid part didn't do a good job, for sure in a normal room this setup can do miracles. Source, amp and equipment were same level, imho top equipment in wrong room.

Hornspeaker System Acapella Apollon

2nd place: Tannoy Prestige, Nice looking and good sounding. Big room with some 20 people inside, high volume, sound live. Good attention to light detail and atmosphere, plus some artifice like tube traps, plus the floor was carpeted. optimal condition

Prestige Range

3rd place: Kef Muon, priced up to 150k $, maybe the best room in show, located in best spot. Tons of substance. Sound was really good, but if I have to be honest, I was not so impressed
