I'm also a fan of every one of the Raidho products. My favorite cost-no-object, however was the Sonus Faber Aida. Driven with all-tubes and vinyl, the sound was ethereal. Also really enjoyed the sounds from Magico and KEF Blades and Wilson. On the lower end, I was really impressed with speakers from ELAC and Spatial. Most missed from last year's show - Acoustic Zen.
Most disappointing speakers include the big Monitor Audios and the JBL Everest(?). Also not that impressed with MBL (just like last year), but maybe they never seem to be playing anything interesting whenever I stopped by.
I mention the rooms by speakers because I find it so difficult to judge the electronics without knowing the speakers characteristics.
