Dinogb,
I've had a Rowland Model 2 for 12 years. I recently upgraded to the Rowland 625. My speakers are Avalon Avatars, similar to your Ascendant.
My current preamp is the Pass XP-20. I still have my XP-10.
I think you should try either one in your system.
The Synergy IIi is nice, but both of my friends who owned one upgraded to the Pass X1 with good results - and the XP preamps sound even better.
