Amp for Verity Parsifal encore

I just got a pair of used mint Verity Parsifal Encores. One of the last pairs made before the Ovations. I am driving them with my Belles amp and preamp which are very impressive. I am starting my homework for upgrades of my phono, pre and power amp. I am also looking at simplifing my system, reducing wires and components to just CD player and Turntable. I also just got a new Naim CDX2 as a cdp upgrade. I am considering strongly the Aesthetix Janus stock or signature as full function pre, possible atlas power amp. I have heard the Nagra PSA with the Parsifal ovations and was very impressed. I am not in a big hurry and am only looking for others thoughts and comments that I will investigate. Thanks.
