If you can wait a little a couple months more, the first batch of Epos is supposedly shipping out next month and according to a local dealer who actually heard it in Munich, there's simply nothing else better at that price point.
3K - 8K new should be able to get you the flagship Triangle Magellan Duetto and AudioVector R1 Arrete. If you prefer more neutral sound you could get the cheaper ATC SCM19. I am using Cabasse Riga, the current iteration Riga 2 cost around 6K for the base/bookshelf version. I love it to bits and it is a very easy pair of speaker to drive, but you need to have a good sub pairing for it.
2K - 4K used I would probably keep a lookout for an used Special 40th or any of the speakers I mentioned above.
