A Swiss company, relatively new, but that has become quite famous quite quickly for its "money is no object" audio solutions with "soul" obviously!
6moons, Hifi News and other experts rave about these electronics, including the recently released 540, a combination of SACD player and HiRes DAC, that will set you back around 35K$
I didn't get a chance to listen to these digital jewels, so I would be quite happy with a 1k$ OPPO player and/or a Metrum DAC in the same price range.

I have always had a sweet spot for Meridian products, and their CD players in particular. Their intrusion into "virtual music" by the acquisition of Sooloos add another dimension to their commitment to reproducing digital files.
Martial Hernandez, DJ extraordinaire, was keeping the audience riveted - to their seats - by his intimate knowledge of any of the 4000 CDs ripped on his 2To Sooloos system. He was helped in this exercise by the beautiful Vienna Acoustics speakers. Certainly one of the most knowledgeable and entertaining demos at the Show!

Sonus Faber has a long tradition of good speaker design in fabulously finished cabinets.
Here, the new Guarneri Memento are driven by the PrimaLuna 35W tube amps, a fine combination indeed, which retained a lot of visitors for more than the average time - I certainly was one of them!
It is always difficult to assess the performance of a speaker at a trade show, but some of them - and the Guarneri Memento is one of them - just make you stop and notice the difference.
What does it for me is the sheer balance, dynamic range and accuracy of this splendidly designed and manufactured pair of speakers, and the pleasure it gives me listening to most music you throw at it - even if they cost 15k$!

An innovative music server, and multiroom system, the Maestro proposed by Soledge, one of these new breed of French manufacturers who embrace new technologies, but still respect the main "raison d'etre" of hifi equipment, which is reproducing music.
They had "borrowed' a pair of KEF speakers for their demos, which were driven by their Tenor  "remote" amplifiers, the signal being transported via the power lines in a 200 Mhz PLC "envelope", quite an impressive feat!
We are far away from the X-10 PLC systems, used in early home automation systems!
