Congrats! Although the MMF7 and VPI Jr. are considered in the same class, I heard both and preferred the Jr. When I auditioned it, my salesman upgraded it to a MkIII right in front of me. Very interesting, easy, and what a difference! That Jr. will be a great table to upgrade--and trust me, you'll upgrade. Upgrading is good! And fun! I was impressed with what a difference going from sorbothane to springs and a more massive platter made! One caveat, the Grado MM that I heard on the MkIII did hum a little. I ended up going another direction and got a Gyro, but I think VPI makes some very nice tables. I'd take one over that MMF7, they're nice but only so much you can do with them, as you found out.
Have fun with it! :)
