Advice on pre-amps needed

Just bought some new stuff (Audio Aero Capitole II; Ayre V-5X evolution and Electraglide power cords). Now I need a very good pre-amp with phono option. Which one should I take?

Nagra PL-P / Aesthetix Janus / Ayre K-1X evolution / CAT Ultimate SL-1 MK II / Cello Encore 1 Ohm ?

Any hints are welcome..Thanks!!
