can I damage my LPs by using a DJ setup -no scatch


Hi everyone,

I decided to go the route of a DJ setup to experiment and possibly entertain with an inexpensive DJ setup. I got 2 Numark TT1625 turntables with the factory cartridges, usually a 0.6 Mil spherical Diamond Tip with about 3 grams of tracking force. I plan on doing playback and back cuing only, no scratching.

Can a cartridge like this damage my LPs that I use on my non-DJ setup at home (in my System link)? If so, should I go to an Ortofon Omega that has an elliptical stylus and tracks at 1.75g?

TIA!

Got the tables setup today tracking at 2.5g. Sound pretty good and not a bad setup / sound for $250 with 2 direct drive tables, two channel mixer with iPod dock, some crappy headphones and a coffin road case. All new equipment. Maybe if I do a paid gig I will upgrade the cartridges...
You shouldn't have any problems. 
Spherical styluses will wear records faster than modern stylus profiles .
This is no good for records.After awhile your records will be history.
The life span of your spherical bonded tip is very short (especially at 3g tracking force with back cueing), you have to change your styli every 150-200 hrs. Sooner or later so called cue burn will appear in the beginning of each song you are djing with (and it will be audible like some sort of pink noise). Those turntables are awful and if you want a proper setup buy Technics mk7 and Grado DJ100i cartridges (or Nagaoka MP200 or related).
