I have to admit I really have no experience with any of the phono stages mentioned here other than the Aqvox (I was an early adopter and own a Mk.1). That being said, I think that providing you are going to use it in balanced mode with a low output moving coil it offers up some very impressive performance and just sounds "right".
I'd agree, also, that it benefits from an upgraded power cord. The very inexpensive DH Labs cord (I did a DIY one with Marinco connectors for $70) works quite well and fleshes things out and warms things up a bit, which was just about Fremer's only criticism of the Aqvox in the rave review he wrote on it. I've heard it also benefits nicely with a fuse upgrade, which certainly won't break the bank.
But don't buy it unless you are prepared to run balanced with a low output coil. That's where the action is with the Aqvox.
