Piega's "New "Spk line: "Improved or Just Hype?"

Piega of Switzerland has introduced a "new line" of speakers.I am curious if anyone has heard the model C-3 which is $3995.It is a short column about 40 inches tall. They claim that they have improved the "ribbon" tweeter and therefore improved the overall sound. Some of their previous models were often considered bright and edgy. Can anyone confirm whether this model line presents "real" improvement over the previous speakers??? Thank you, SJ
