The Technics SL1200G is a good machine- you can spend a lot more and not get as good.
You're going to have to have a phono section too. A good phono section will have less surface noise (with actually wider bandwidth) than a bad one. Most people don't realize it but a lot of ticks and pops originate with the phono section and not the LP surface.
A low output moving coil cartridge will have more bandwidth- but you need more gain. What you will find with cartridges in general is the ability of the tone arm to properly track the cartridge is far more important than the actual cartridge you get! Setup is probably the biggest downfall of vinyl, but if done properly the result makes it hard to go back to digital.
