Requesting recommendations for phono stage


I have a Primaluna Dialogue Premium Integrated amp with built-in phono stage.  My cartridge is a Clearaudio Maestro MM.
Can I improve significantly on the sound by getting a separate phono preamp?
Looking for recommendations.  My budget is $1,500 plus or minus.
Thanks!!

@600ohms thanks for the clarification, Mr. Herron. I sent you an email earlier today. 
Keith - thanks for taking great care of me and others! The wood faceplate is lovely as you know :-)

@bkeske. Yes. And was happily surprised at how much of a difference it is from the already formidable as LFD LE I have. Still burning it in. 
@chakster TBH, I tested the gold note and the LFD side by side in my system for about a week and with several listening buddies over, and the LFD simply destroyed the gold note no matter what settings I had the Gold note on. It's a fine preemplifier, and it has a lot of flexibility, but I was surprised at how inferior a performance it was compared to the LFD. But then again, that was just one side by side in one system, so obviously not applicable to everything
