Before switching to Mullard EL34 XF2 a few months ago I was using SED Svetlana Winged C's in my VAC Avatar SE integrated. They were alright but nothing more, the Mullards are far better in every respect. Besides, one SED failed after 700 hours, I bought them new from Tube Depot, they still have them for $120 each.
If you want to try new production EL34 you might try Russian Mullard reissue, many like them more than SED Winged. They are something like $50-$75 each from Upscale Audio or other places.
I personally have absolutely no intention of buying any reissues.
