How long does the belt last for?
Not sure - I would say depends on the climate. I haven noticed any difference in performance, speed variation or any change in the Belt in three years of having the DPS.
I must of gotten one of the last DPS turntables in Australia because the guy who sold it to me had an extra bearing and an extra uncut acrylic armboard.I guess the previous owner ordered the extra board and bearing to be able to install a different arm at a later time (since the whole top with bearing is changed for a different arm).
