Pass Labs XA 30.8: how does it compare to the power section on the Int-60?

Hi,

I had the chance of auditioning the Pass Labs Int-60. It is an amazing integrated and much, much better than the previous "point 5" series. I auditioned the Int-60 because the XA30.8 was not available.
The specs at the Pass website do not provide a direct comparison between the power section of both amplifiers. I sent a message to Pass without feedback so far; a search on the web did not provide me a clear answer to this question. 
Can anyone shed some light on this topic?

Thank you!
Joao
