Initially I was using Focal Diablo Utopia III speakers but lately I prefer the musicality of Harbeth M30.2. I still use Focal Diablo for multi-channel.
Active crossover changed to JL Audio CR1, which is more transparent compared to Bryston 10B-SUB and without any hissing noise of the 10B.
Nice system...I've heard a few stand mounted speaker systems sound absolutely fantastic...they do have some advantages in imaging given the cabinet get's out of the way of the sound...congrats on very cool set up !
