External phono stage for Luxman 509x

I have a Luxman 509x on the way. I’ve heard it has a good mm/mc phono stage built in. What would it take in an external phono stage to beat it? Would something like a Parasound Jc3+ be better and why? 


I’m not sure why this post is all the sudden gaining traction again. I asked this question a month ago. Received the 509 a few days after the post and then the next week I purchased a Parasound JC3+. The luxman phono is good but the Parasound is definitely better and of course way more flexible.
