Looking for a phone pre to go with my McIntosh MA-6600.

Have always wanted to try a moving coil cartridge with my system which includes a VPI prime currently with a Ortofon 2M black.  I want something which is well matched to the Mac which has an input impedance of 20k ohms.  I see this is lower than most so will it impact what I can match with this receiver?  Looking to spend no more than 2-3k on the top end.  I want it to be flexible enough as I am not sure yet on cartridge.  I am figuring $1-$2k to start.  Thanks.
