The design and features of the top Vandersteen models are fantastic; they are very adjustable and livable (but heavy) like the hybrid Martin Logans. At their price, the 5As are less compromised than the Summits. Short sound but they are coherent and dynamic and more engaging. As a feature-driven, total package question, could be any easy call, but with $30k my mind can't help but wander. Considering sound only, the 5A Carbons have real competition at that price point.
