Why on God's green earth would you need a turntable in a secondary system?
I have a secondary system that I have been using to play grade all my records and get them entered into the Discogs database.
It's no slouch. The analog chain consists of Simaudio 600i, Harbeth P3ESR, Power Sound Audio S1500 subwoofer, Manley Chinook phono stage, JVC QL-Y66F table with an inexpensive Denon DL-301 MK2 cartridge.
Why limit yourself to one system?
To the OP, as long as the cartridge is made well and set up properly you shouldn't damage your records.
