It's it too late to buy a Jeff Rowland Synergy 2i preamp?

I’m using Avalon Opus Ceramique speaker,  many people said Jeff Rowland is perfect match with Avalon speaker but I never try. I’m think to get a JR pre-amp, but brand new Corus and Criterion are too expensive, 2nd hand product is hard to get at this moment (also expensive). May I know if Synergy 2i sonic characteristics is very close to Corus and Criterion? If I can get a good price, is it too late to buy a  good condition Synergy 2i now (around USD 3500)? Also does it match with my power-amp Electrocompaniet AW-180? THX
