I need an amp, can any recommend?

I would consider a Parasound Halo A23 (A21 if you want/need more power), or with the sensitivity of those speaker maybe a tube amp such as a Prima Luna?

The Wyred for Sound are supposed to be great, I have not heard them personally, but everyone I know who hears them loves them.

Also, you may look at some of the previous generation Bel Canto amps, lots of power, smooth sound, and tons of operational flexibility.

good luck.

I second McCormack amps-very musical.

What is your budget and room size?

Your speakers are 90 db efficient and 4 ohms nominal impedance. I haven't heard that model, but the KEF speakers I have heard are reasonably bass-heavy and benefit from clean amplification.

I third the suggestion of the McCormack, and would also add Monarchy SE-100, Musical Fidelity A3.2cr, and Classe CA-100.

It depends largely on your budget and listening preferences.
