ARC REF2 phono vs REF2 SE version

Anyone out there compare these two phono's, if so what were your thought's.

On my short list to hear ideally in my own set-up.
There are already threads on this subject. Search the Forum. Also Jonathan Valin has a blog on the subject too. From what I've read, the difference is a significant improvement. I'm on the "SE" upgrade list for my Ref 5 line stage, which also has threads running here. Same difference -- very significant improvement. The SE upgrade in large part includes custom proprietary teflon coupling caps and a super beefed up power supply.
Really, can you provide links because I did a search prior and nothing substantial came up.

Don't really car too much about part, sonically is what interest me.
Dev, here is the absolute sound J Valin review link:
