In need of advice on speaker choice


I have a Yamaha M2 amp with a C85 preamp and am looking for advice on pairing speakers with it. I see a pair of Keff r900's for sale at $2,500 but have not listened to them yet. I have another system with JBL L-65 speakers which I love.
There are so many options out there and I don't know enough to make a good decision. I am looking for used but do not want to spend more than $2,500 for a pair. Any help would be greatly appreciated!!

You are going to get 100 different suggestions. Your best bet is to hit all the audio stores you can,and listen to as many different speakers as you can. You will need to pinpoint what kind of sound you are looking for. Take your time,and enjoy the ride. 
Thank you, that makes sense. It's time or lack of it which queried the question. But listening seems to be the only real option since every ones taste is different. I suppose more directly is the Keff r900 worth $2,500 used and sound wise are there better alternatives.
I second sticking to JBL - L100, or even 4430 used. I am listening to them now, and they are quite special with alnico magnets - unlike modern offerings...You can find a clean one on ebay sometimes, or craigslist.
