Interesting that SME seem to have made rods for their own backs with this one (I'm sure it doesn't need to be as complex as it is). The one we had in 2003 or so sounded very good indeed and didn't seem to have any speed issues tbh.
I still think that decks like this are priced for cachet rather than performance. I mean, a Dias should run at the right speed, the belt doesn't usually deform or stretch over the years and it's as near to fit-and-forget as I could imagine.
Tear down these walls; Cut the ties that held me
Crying out at the top of my voice; Tell me now if you can hear me
