Want new phono amp, what should I buy?

I have a Sota Star Nova turntable with an SME V tonearm and will soon have a Sota Cosmos 4 turntable. I curently have a very low hour Zyx 4D cartridge with the Gold Coils, Purist Audio Designs 1.2m Venustas Rev C tonearm and a Zyx Artisan Phono amp. The rest of my system is Pass Labs XP 10 Pre-amp and a X350.5 power amp with a set of built to the max True Soundworks (Rich Murry) Apogee Duetta Ultimate Signatures speakers. I think the weak link in my phono rig is my phono amp. I would like some recommendations for my audition list?
