@tls49 , +1. Does the OP have a very large room, or listen at very loud levels that would require more power? Remember, doubling power only adds 3 dB.
Personally, if I were looking to split this integrated amp up, which I am not saying is even necessary, I would look to add a tube preamp and use the B100sst amp section.
