Jfrech and Dennisb,
I will second Jfrech's statement about there not being a phono card available for the vk50's and 51's. I also have VK50se and I am currently using an EAR 834P phono stage and they work very well together, however I am starting to look at upgrading the phono stage for reasons I will explain below.
Another point to consider is that the 50's and 51's are balanced inputs only, so it might be worth limiting your choices to phono stages that have balanced outputs, assuming that the phono stage in question is truly balanced. I am having to use a balanced-to-s/e adapter with the 834 and I do wonder how much potential there is waiting to be tapped by moving to an all balanced system. Of course, balanced equipment will drive the price up a bit.
