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.
Sooloos by Meridian
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!
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$!
I would recommend you reading a proper review by Michael Stremer in Stereophile: http://www.stereophile.com/standloudspeakers/807sonus
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!
