Somebody is kidding somebody here..we need to consider price per improvement(?) here..better to have the platter modified to be flat and keep everything else the same, my money is that the flat platter is the better upgrade, did similar with my Beogram 4000 ( only using an old 12" "stiff" record to do the job and tracking angle notwithstanding, a huge improvement). Grado are good....but not that good.!
