JRDG Jeff Rowland amps with Shahinian Diapason?

Hi,
i have a Jeff Rowland Consummate, 2 Bedini BA 803 in biamping modus and Shahinian Diapasons and thinking about upgrading the amps.
I read much about old and new Rowland amps, even about different Plinius, Pass, etc. amps.
Unfortunatelly i had so far no chance to try any of them at home in my own system.

Have anybody heared old (7, 8, 9, 12) or new (201, 301, Continuum integrated, 302, 301, 312) Rowland amps on Shahinian Diapasons (or Hawks)?

Thanks for any information
