phono preamp for Primaluna

A couple of years ago I picked up a Project Tube Box DS for $350 and it sounds surprisingly good while being quite versatile with MM and MC settings.  MC gain goes up to 60dB.  I see it's been replaced with the next model (DS2) for $700.  I wouldn't pay $700 but you can find these units on sale often and used or demo versions.  For MM only carts I hear good things in this price range for the Lounge LCR Gold.  For MC only I'd go with the Tom Evans Microgroove in this price range.

Here ya go!

Try a used EAR 834P! Might cost a bit more than you list. 

How about the Bellari phono stages? Two models available: VP549 ($149) and VP130 ($275). SS and tube (12AX7), respectively. Both are MM only. Bellari does make a SUT for low-output MC cartridges - but for an additional $500. I have the SUT. Excellent quality, made here in the USA (Utah). Check on EBay for sellers.

This one has impressive specs and features for that price point:

For a little more, consider the Elac PPA-2.
