Have Mac mc 60 - need Mac premap - suggestions??

Am new to this stuff - have yet to earn my audiophile stripes, but I am trying - most importantly I am having fun and really enjoying getting back to a way of life that I enjoyed 40 years ago...

I bought a super clean pair of McIntosh MC 60s... why - because I wanted to, I love and collect antiques, I was told they sound great, and they are cool as all get-out...

I now need a premap - want to stay tube, but want to use this stuff - want it to sound great - either Klipsch Heresys or Advent Large at the other end... a B&O 4004 turntable and Revox B-77 will be the sources - will want to add a cd soon...

Any advice as to what I should be looking for in the way of a McIntosh premap?
thanks
