Hi sjh500 & Vinnie,
I have owned Reference 3A Royal Master Series II monitors and paired them with RWA Signature 70 monoblocks and loved the combination. It was some of the most pure sound I have heard in my system or others. It was a fantastic pairing. I think you would be hard pressed to find a better amp with Ref 3a speakers. The fact that Vinnie gives you a 30 day trial period. I doubt you would be sending the Sig 30.2 back to him.
Good luck on your search
Nick
