This week, I was able to hear the Focal Aria 948's which use the Flax drivers and they sounded great. They sounded better than the Sonus Faber Venere S and the SF's were connected to all Mac gear including a Mac CDP, while the 948's were connected to a $2700 Sony AVR and a Sony DVDP. Of course the detail was much less with the 948's given the electronics and source but the sound was definitely more pleasing. Both sell for $5K.
The 948's are definitely on my radar to replace my Magnepans. I am not sure about the SF's as they sounded sharp and hurt my ears with vocals at louder volumes.
