KEF R107/2 vs REVEL f52

My kef's are getting a bit long in the tooth and am looking for a drop in replacement for them, The 107's were amp friendly unlike many other kef models they only needed power to come alive not incredably expensive power. so I can get a pair of F52's for a fair price and want to hear about them.
I guess you need to ask yourself: "Self, what is it about my KEFs that I do not like and would like to improve upon?" The KEF 107/2 are very good speakers indeed. As are the Revels. But this is beside the point.

In the $6k - $8k price range, there are a *jillion* (mathematical term )) speakers to choose from. And most of them are very, very good. The only honest way to tell if the Revels (or any other speaker) are a suitable replacement for your KEFs is to get them into your system/room side by side and conduct a shoot-out.

Otherwise, you will need to visit dealer after dealer seeking the Holy Grail of Speakers for you. Even then, you will still need to hear them in your system/room. There is NO way to shortcut this process - sad, but true.

I wish I could be of more help, but what you are trying to do cannot be accomplished by listening to what others have to say. You have to do the heavy lifting (listening?) yourself...
