I'm using a Hagerman Bugle phono pre-amp and power supply that I built from kits. I have since swapped out the three original op-amps and replaced them with the LM4562NAs. I think they added a blacker background for the sound. Ever the tinkerer, I wonder what your new SS Audio OPA will do. Sure, I understand I will no longer be able to stack phono pre-amp and power supply as I do now, but part of my longer-term goal is to house each piece in separate boxes.
