Another option would be the Ayre K-1XE. This preamp is very well reviewed by the Audio magazines (both on-line as well as print). Used they go for under $5K, (and closer to $4K if you only want the line stage, although, the optional phono boards are well worth the price of admission). If you must buy new, (your post said the preamp should "retail" under $5K), the K-5xe is also very good, and would meet your budget constraints.
I use the K-1XE with my hybrid amps, the Lamm M2.1s. They work very well together, IMHO. (I believe I am done looking for amplification equipment for a very long time.)
Good Luck in your search!
