@reidcc In your case, having owned both, properly broken-in, I would strongly recommend the Zen Phono with iPower X power supply. You have an excellent cartridge which, I suspect, you have no idea how good it can sound. The above mentioned combo will be a game changer for you. I made the same recommendation recently to an old college roommate from 5o years ago and he was delighted.
No need to spend the extra money on the iPhono3 unless you need the added features which, I believe, you don't.
