I am surprised that you found the Nagra VPS so disappointing . There are many here on Agon, including me, who have been consistently pleased with its performance. What was the cart loading used and did you use the tube or the SS gain stage ? I don't agree that the VPS doesn't work with LOMCs. Have used it with a 0.3mv Orpheus L and now with a Lyra Atlas and the results have been pretty amazing to put it mildly. I guess to each his own.
Best of luck in your endeavours.
