The Esoteric 30 watt Class A amp makes these A5's sing !
glupson I dare you to prove to me right now that the Magico has better measurements than a cheap speaker. I dont care how much effort went into making the Magicos. It all comes down to whether the Magico is superior or not.
So you ask for measurements to prove that Magico is better than a cheap speaker. Then in the same breath you say "Even superior measurements are worthless"......
Are you a politician by day, and a high end speaker basher by night?
I am extremely impressed with the sound produced by the Magico A5 speakers. The midrange is excellent and an improvement over the A3, the bass is tight, clean, and sounds effortless like a well-integrated high-quality subwoofer, and the soundstage was wonderful.
At ~$20k the A5s are a very, very attractive value proposition.
As for measurements, anyone can refer to the SoundStage! Network and Stereophile data to compare against other speakers. What I (and others) hear backs up the superior quality implied by those measurements.
