Preamp recommendation for EAR 509


Hello everyone!
I´m a regular reader but this is my first post.
I´m looking for a tube preamp for my EAR 509 monoblocks.
Price about 3.5k, new or used.
Any experience or help will be appreciated.

The EAR-Yoshino 868L, a nice line stage sometimes available for around your price. In fact, there was one listed on Audiogon a couple of days ago (not from me!).

Thanks bdp24,
 I saw the 868 and is one of my options.
I would like to know some other experience  with other brands  that were a better choice and a good match with the 509.
I appreciate your advice
I hope I could make myself understood because English is not my native language.....
