The Fi "X" would be on my short list. Get the Magnequest OPT upgrade for best results. Also, if you're handy with a soldering iron, the Bottlehead 2A3's & 300B kits are supposed to be very nice parallel feed units in the 1-1.5K range.
SUN 2A3 single ended triode.....
This unit was highly touted by Sam Tellig in stereophile. I cannot get another review of it anywhere. I am looking for a SET and dont want to spend big $$$$$$ on diminishing returns. Any reviews? Any other SET in the reasonable ($2500 used, $4000 new) range??? thank you
