Congratulations on the big step to krell! I'm always turned off when someone slams one brand then follows up with recommendations of what they have. The early b&w was voiced in that more traditional British sound that needed proper components to come alive. I expect the krell gear will 'wake them up ' personally I would recommend getting to know this new system b4 spending another ndime
Playing with roe in and other placement options will make as much difference as cables. Enjoy
