Pass Int-150 or Int-30A for PMC Speakers?

I have listened to PMC speakers (GB1i, FB1i, OB1i) with various integrated (Bryston B100&135, Simaudio 340i, Krell s300i, NAD M3) and was not closed to being satisfied. So I have decided to splurge a little to get Pass Labs integrated. Has anyone tried Int-150/30A or their amp version (x150.5/XA30.5) with PMC FB1i? What's each combination like?

Seems like many people match OB1i with Int-150 but am curious to hear what PMCs sound like with the Pass Labs Class A setup...

I will be using NAD M51 as DAC.
