Would be interested to hear John DeVore's thoughts / preferences between the two amp in question.

John Devore has already commented above:
if the XA-60.5 is remotely close in price to the X-350.5 go for the XA. It will sound enormously powerful on the Nines and will have subtlety and nuance the AB amp lacks.
Happy listening,
John DeVore

More than anyone, the company owner should know how an amp would perform on the Nines .
