If its .65mV that's medium output not low and just about any phono stage will have enough gain. For around $1k you should be able to find a good used Audio Research PH3SE, a darn good phono stage, good enough I was very happy with mine for a good 15 years. Only upgraded to Herron VTPH2A two years ago. My PH3SE was used with medium output Benz Glider, Ruby, and Koetsu Black Goldline, all with nearly identical output to yours.
Other than that there's lots of good new phono stages for under a grand, and as others have said they will ALL be a massive improvement. Massive. As in what you heard going to the VPI that made you so happy all over again. Just like that.
Don't forget though that with a phono stage you will also want to use a very good quality interconnect.
