I own both but cannot compare them, because different plinths, tonearms, and cartridges. And they are connected to two entirely different systems, one feeding Beveridge speakers (TT101) and one feeding Sound Lab 845PXs (DP80). And, the DP80 sits idle in favor of the SP10 MK3 and Kenwood L07D.
It would be a close call. These days, I am biased in favor of coreless motors, so the TT101 gets the nod from me in my Beveridge system. That said, the motor of the DP80 was state of the art in its day, as noted above, and probably on par with any motor still being made for DD turntables, as far as that goes. It's a little smaller than the motor used in the revered DP100 and DP308, but it's as big as it needed to be for driving the DP80 platter with precision. Peter knows more about DP100 and DP308 than I.
