Because they are critical favorites! Seriously, the new issue of The Absolute Sound arrived and the Maggies swept some good rankings in the new Recommended Products list. 20.1R - Class 2 Speaker, second highest recommendation (Best Buy) 3.6 - Class 4 recommendation (price range from $4,100 to $12,000) 1.6 - Class 2 (Speakers under $2,500) (Best Buy) I have had the 1.6s and the 3.6s and highly recommend both. For the money, its a great speaker! P.S. The 1.6 is around $1,600 per pair and the 3.6 is $4,200 and for you wealthy types, the 20.1 is $11,500.
