I have the INT-30A, and use a BPT PC to good effect.
If you read around here, I think you'll find that Pass stuff has the reputation for being relatively insensitive to PC changes, and as I recall the Pass literature suggests the same.
But when I ABed the BPT against a lower end PS Audio with a friend who is a power cord skeptic, the superiority of the BPT was evident to both of us.
So I'd think you might well see improvement with PC changes (though I can only speak first hand to the integrated, and not the power amp).
