I'm a newcomer on these threads, so hello to all and sundry.
I upgraded my Technics recently. Visited the local London hi-fi shop who gave the usual pseudoscientific criticisms of Technics / DD turntables ("abused by DJs", "constantly hunting" etc) and offered no help whatsoever on a suitable choice for cartridge, so I had to go it alone. I went for a basic upgrade consisting of OL plate, RB251 and Denon DL-160 cartridge with OL upgrade mat sitting upon a Project cork mat.
Honestly, very rarely have I heard a true 'night and day' difference in hi-fi like this - the improvement was staggering. I found you get a great combination of the detail and punch of the Technics, with the smoothness and neutrality of the Planar 3. I'm certainly with DP on this one!
