I seriously prefer the AD8610 to both 627/637 in a RIAA application. It sounds much more dynamic and alive to my ears. Plus it has better DC performance which saves the o/p cap.

No immediate comparison to a 709 though, can't get free samples

Try the AD825 which is a single OpAmp. I like it a lot. You would need a SO- to 8 DIP adapter.
See here: http://www.brndog.com/priclist.html to get such adpters.

I also recommend the 604, which is cheap, and not too bad.
