My final show preference...top 10 rooms:
1) Aries Cerat. Most realism in a system of still "fit in your home" size.
2) Acapella but you needed to sit in the first couple of rows...further back was far less appealing
3) Cessaro with Opus 1 + subwoofer: However, the big system was not very good...no idea what the issue is.
4) TotalDAC. Maybe some rooms sounded better in some ways but the sound was clean, fresh, well balanced and dynamic. Good value by show standards
5) WE room with Silbatone. Not quite as good as some past years and somewhat uneven but unrivaled dynamics and emotion
6) Sigma Acoustics with CanEver eletronics and a big TT. Really lovely and dynamic sound...best system with no horn driver of any kind
7) Grandinote. This was the best under 50K system at the show IMO. 98dB speakers with compression/horn tweeter and Magnetosoild amps
8) Living Voice. Very good sound but perhaps not great value for the speakers (52K). I think the system could have benefited from having more than 8 watts of 300B power on tap as you could hear the strain when it got loud.
9) Diptyque. Best sounding panels at the show, IMO. More coherent, tonally balanced than others. Being in a smaller room probably helped in this case. Was very good last year as well.
10) Kawero! + Ypsilon. Most dynamic non-horn system. Last year had too much zing in the tweeter but this year it was yummy.
Honorable mention:
Von Schweikert/VAC. Very dynamic for a non-horn system and extremely resolving. However, was not very forgiving of lesser recordings
ESD Acoustics: Bombastic in the same way a Buggatti Veyron is for cars. Loved the ambition and scale but for anything other than big classical it sounded overblown.
Tidal: Didn't hear the Buggatti model but their other bigger model was quite warm and natural sounding even with SS amps
Voxativ: Often I don't like the highs of whizzer coned drivers but they had a new black coned driver that sounded very good with midbass coupler and dipole sub...
Fleetwood Sound: Lively and fun but a bit raw sounding at times
Diesis Audio: in a much bigger room this year and it didn't really work as well as the past few shows. Still lovely sound but lacked some impact this time
Soundspacesystems: Funky, high sensitivity speakers that were a lot of fun...but way overpriced IMO.
Odeon + New Audio Frontiers: Was great when they picked good music...which wasn't that often.
Jadis + Davis Acoustics. Prototype speaker was good fun and lively...Jadis has lovely voicing.
Thrax: Great sounding monitors and all 300B preamp/amp chain.
WLM: Small two-way speakers were a real surprise for reasonable money
Marco Serri design: Crazy stuff with an appealing an lively sound...perhaps not completely worked out designs but a lot of fun.
Almost but not quite:
Boenicke Audio: Had it's moments but overall seemed a bit uneven
Marten: All rooms. Speakers had strong bass in both rooms and overly soft upper ranges.
Wilson/Nagra: Had considerable strengths but just doesn't sound realistic
Wilson/VTL: same as above
WE with new (as of last year) speaker
Avantgarde.Duo GT..something about them with SS amps just leaves me cold.
hORNs: Didn't really gel for me
Goebel + CH + WADAX/Kronos: With Kronos it would almost have made the honorable mention list but I think CH holds it back. With WADAX, no thanks. The whole system was significantly better last year with True Life Audio amplification, IMO
MBL: Always a "not quite" for me because of the metallic nature of the overall sound I always hear...strengths are clear but i guess not everyone hears the weaknesses.
Bayz: Could hear the "pipe" overlaying the sound...otherwise nice boxless sound.
Stenheim + Dartzeel... a bit "meh" but basically ok
Rockport + Absolare: not sure what the fuss is about...ok hifi sound.
Brodmann + Viola and crazy Zensati cables; Interesting and almost made honorable mention
Fails:
Wilson + CH...ummm...bad
Kharma room....ummm....really bad
Kharma + Robert Koda + Wadax (?)....umm...really really bad
Wolf Von Langa + Air Tight: Very thin sounding
Clarisys + Soulution (would like to hear them with something less analytical) very cold and analytical sounding
Alsyvox + Pilium: (last year lacked dynamics with Jadis and this year lacked soul and coherence with Pilium). Liked their sound a lot in 2018 and 2019 but not since they came with the big speakers at the big show. This is perhaps not quite a fail but after great demos in the past the last two years have been a big letdown.
Lot's of other rooms that left no impression on me at all.
