I don't know the Audio Note, so I can't comment on that. I've heard the MMF7 and it is NO contest to th Gyrodec IMHO. I hear the VPI Scout is an outstanding 'table if you don't mind an unsuspended design. The VPI HW19 Mks III and IV are both very good, too, as far as I'm concerned.
I love my Gyrodec SE and would highly recommend it. Got mine used at a very affordable price...the sound is stunning. As far as upgrades, VPI HWs are easy and relatively affordable to upgrade; Michell also offers good platter and PSU upgrades for the Gyro, and they work very well with SME as well as Rega and Rega-style arms (I put an Origin Live Silver on mine) and of course there are a zillion mods for those bad boys.
My $.02
Good luck!
