ARC PH 3 SE vs PH 7

I recently found my way back to analog thanks to some of you here. I have resurected my limited LP collection and am purchasing more new and used LP's as I go. I started out with a Bellari 130, then moved to a ARC PH 3 SE. The difference is night and day. I have a new Clearaudio Emotion TT with a Maestro cart. I'm already looking to possibly upgrade my phono stage preamp, but to what? Love the sound of my PH 3. How does it compare to the PH 7? Or - any other recommendations?
