If you use a tonearm with a removable headshell, you could swap in a heavier headshell to increase the effective mass. E.g., I have a Technics SL1210M5G. The stock tonearm eff. mass is 12g with the stock extremely light 7.5g headshell. The LPGear ZuPreme headshell weighs about 14 g, so that increases eff. mass to 18.5.
Another approach would be to get the Zu103, which with its solid aluminum body weighs quite a bit more than the stock DL103/103R.
