I think you know the answer to that, don't you @pawlowski6132 ?
What's your overall budget? What kind of sound are you chasing? Do you have a preference regarding speaker types, e.g., planar, dynamic, horn, etc? The amp and speaker relationship is an important one and if you are doing LP playback, I think you'll get a fair amount of feedback about buying a decent table and arm, along with a decent phono stage, and working your way up through cartridges gradually. Though I use fancy wire in my main system, I did very basic wire in my second system (which has an entirely different character) at minimal cost.
Used can be good if bought from a reliable vendor and can save you money.
I'm not sure I can provide much more without a better sense of what you've listened to, what you like and what your objectives are. I'd rather hear a well set up modest system than a bunch of expensive components thrown together.
You can take it on a theoretical level- source first, weakest link- or make it more concrete. I think the latter is where you are going to get more help, but one can have conflicting views on almost anything, so I offer this as a modest proposal to provide more information about your listening preferences. (I know, systems should be agnostic and accurate and all that, but if you are listening to death metal, I doubt anybody would recommend Quad ESLs). Note: I listen to death metal on old Quads. But not exclusively.
