A new review of the Alexia was just published in Positive Feedback issue 76.
My favorite comment was this "the ultimate goal at WA is to not build a speaker that obediently follows a frequency response profile; we want it to sound like real music”.
The conclusion was "Alexia then is something special. Unquestionably, Wilson Audio has created a future classic. My guess is that in time, Alexia will go down in history along side Watt / Puppy (Sasha) to leave a permanent mark on the entire market that is high-end audio."
