I own and use both the FPB and the KSA 300's. No doubt about it, the FPB is MUCH hotter than the KSA.
When both are just sitting with no music, but in the on position, the KSA300S is actually cool; not so with the FPB300, as it is quite warm. When playing music, the KSA gets warm and the FPB gets hot.
But.........the FPB is overall a far better amp!
