Amp recommendations for KEF R7 speakers

definitely a smoother aounding amp like McIntosh sounds best with the KEF R series.  They can sound metallic to some with the wrong amp.  

What sound characteristics are you looking for, what’s the rest of the equipment in your system, what’s your budget, and are you looking for new or used?  Are you looking for an integrated amp or separates?  The more info you provide the better and more targeted the recommendations here will be.

There is a place to put photos of your system under Virtual systems. It would be really helpful so we can be helpful.

A good friend is running a Mac solid state integrated with his Meta 50 speakers and they sound fantastic.  I had heard the Meta 50’s elsewhere with a non-Mac integrated and I found them a bit shrill.  Definitely, the McIntosh amp is a good match.  

I am powering my KEF Reference 1 Metas with a pair of McIntosh MC 611s and a C2700. They sound outstanding. The KEF tweeters can sound a little brittle with the wrong amplification, as others have stated. I don't think you can go wrong with McIntosh for them. Pass Labs might also be a great match.
