Will the Audio Technica one slot straight in?
You'd need to remove the tags/wires from the back of the old cart with tweezers, unbolt the old cart and remove it, fit and align the new cart, reconnect the wires and rebalance the arm. You'll need a protractor that's right for your arm to line it up. Basically the cart sits dead straight in the headshell (The bit on the end of the arm the cart bolts to) and you move it backwards or forwards to the correct overhang for that arm (The distance between the stylus tip and the centre of the platter). To be honest, if you look at where the old stylus tip was and guess it you'll not be far away ;0)
If you do this be aware that the wires are colour coded but the position of the pins on carts is not standardized so the wires may not connect in the same positions as they did on the old cart. You may need to adjust the arm hight too. What deck and arm is it?
The Goldring is a good bit better than the AT. You might well notice the drop in quality, depends on the rest of the kit. If you buy any 1000 series Goldring stylus it'll just plug into the front of your old cart and you're away.
I needed to replace the stylus on my deck - which was barely cheaper than the whole cartridge!
It's often not worth it. For quite a few years now I've been using Denon DL103 moving coil carts as they sound miles better than the MM carts at that price and don't cost any more to replace that a decent MM stylus. You'd actually have to spend quite a lot to see a significant improvement of the Denon, they're great value.
