First that isnt a outboard crossover in the Vandersteen 5A its a Hi-pass Filter, second that is an optional finish. The Aesthetix amp on order was built with input from Richard Vandersteen so the filters are built in, it saves you the $700 for the external filters. Used the 5a has been sold as cheap as $10K range and again worth every penny.
Legacy Focus can be had alot less then $13K,dealer demos go for less and used on Agon I see them for less than $10K.
Roger Sanders is back in business with his own venture but in past conversations was interested in bringing back Innersound after the idiots that forced him out then ran it into the ground were done doing their damage, I own a pair of Innersound Eros but I dont run them in my system.
