Russ:
One of the main benefits of going with KCT + FPB CX amp is the CAST connection. However, the CAST has no sounds of its own and bluntly honest - resulting in no warmth or sweetness if there weren't any in the source to begin with. I sometimes switch back to the normal balanced connections get those qualities you seek but I prefer the CAST connections at the end.
So if the warmth and sweetness in sound is a critical sonic characteristics, I would stay with the Modwright gear.
