Best Phono solid state under 2K?

If you run your cartridge using balanced cables, (I do), you might consider the Ayre P-5xe. Used it runs around $1,500. It is basically the same as the phono stage in the Ayre K-1xe, (albeit just a bit better sounding, according to Charles Hansen of Ayre fame). I own the K-1xe, and the phono boards are near reference. (The only phono stages that better it cost double to triple the price). However, Ayre equipment is meant to be run in balanced mode to take advantage of its design. So if you don't run a balanced system, you might not get all that this phono stage is capable of.

My two cents worth.
Good Luck in your search!

In response to Rdavwhitaker's query, if you're using a really low output MC cartridge, you might be better off with a decent quality solid state phono preamp, as there will, "typically", be less of a noise floor than with a tube preamp. (That is one reason why I prefer having a solid state preamp, and having tubes in my amp.) My Dynavector XV-1S cartridge, (0.3 MV output), has no issues whatsoever with my solid state preamp.

Another two cents from me.
