...but honestly i don’t care about it, can’t remember when i’ve been using a rubber mat last time, normally i replace them with my favorite SAEC SS-300 (lightweight) or heavy Micro Seiki CU-180(or superheavy CU-500) depends on the turntable torque and platter.@chakster I have the SS-300 too, and use it on most TTs, preferring it to rubber. But there's an issue with the DP-80. The platter is in two parts, isolated from each other, to keep all bearing/motor noise from reaching the inner part where the LP/stylus do their thing — it's quite different from the split-platter on an LP12 and others where the 2 parts are in direct hard contact with each other.
Both the 300 and CU-180 interfere with the platter's design. Though the DP80 has ample torque for the CU-180, it interferes the most. I suggest the SS-300 is better suited: it has a cut-out on the underside at the edge, so it doesn't contact the outer platter at all.
