\Welcome!
You need the following chain:
Cartridge => turntable => phono pre => preamp => amp => speakers
If you have enough system gain you can combine the preamp and amp as an integrated amp. The efficiency of the speakers will help determine what is needed in terms of power for the amp.
BH has great phono, preamp, amp and integrated amps kits. You need to set your budget and amp power requirements.
