The 3.7's are a substantial leap forward over the 3.6's and even to the level where the previous top-of-the-line model, the 7.2's were deemed no longer relevant.
I own a pair of 2.4's, and yes, the 3.7's are way better, but also way more expensive and demanding. If you have the room, electronics and of course money, the 3.7's are a real bargin.
