3.6s will be my next upgrade after the amps and universal player. My 1.6s will be moved to the rear and replaced in the front by the 3.6s. My MC1s are going to get used in the bedroom for a 3.1 mini HT. I've noticed a big difference in the 1.6s over the MC1s with both music and HT. I've heard of the Van Alstine stuff, but I've never auditioned any of it. I'm sticking with my Exodus amps.
