Hi hockey4496,
Not sure that I'll be a help here... I've seen raul chime in saying that your table is already better than a Technics 1200. I have no direct experience with your model. I have had A DP59 and a DP60L at my home for a few weeks each while I worked on them, one for a friend the other, my brother....I have never compared either to a Technics. The 59 was gorgeous, but being sonically better than the Technics, I can't say that this is clear to me. The DP60L was clearly a nicer table than the 1200 when I was finished... it had interchangeable arm tubes for cartridge matching. I had added damping all over that table as strategically that I could to kill resonances, which was tough, it had quite a bit of electronics inside. As far as platter mass/weight.... I would add weight without worrying much. I'm in the U.S. So I think in ounces and pounds over grams, but 361 grams is only about 3/4 of a pound, that should cause no issues at all. Start up could be ever so slightly slower, but I doubt you'd notice... I personally would take some butyl tape and layer it thinly on the bottom of the platter also. It helps kill resonances from the motor projecting through the platter.
