The Amati Futura are just wonderful speakers. I have heard them paired with Pass 60.8 amps. I would imagine they would also work fine with your Jeff Rowland amps. I have not heard Jeff Rowland electronics in a very long time. I own a pair of the SF Elipsa SE Reds matched with ARC Reference electronics. This is just a magical combination.
Make a long term plan and work toward it. Decide what Amp and preamp combination you like and ultimately want to use. AudioAficionado.org has a Sonus Faber Forum. It might help give you some ideas on what works well together.
