Greetings!
I’m relatively new to audiophile level equipment myself but have a couple suggestions with links to Steve Gutenberg’s reviews. As mentioned above, he’s a pretty well known and regarded audiophile and reviews a lot of low-mid priced gear in addition to the higher end stuff
Speakers- Klipsch RP-600Ms are efficient and very highly rated Bookshelf speakers. A pair will cost ya about 500 Bucks.

https://youtu.be/0V5nZWWHh48For the Turntable I use a Pro-Ject Debut Carbon still. For the money it’s decent and comes with a Cartridge. 400 bucks.
for your cables, check out this guy:
https://www.schmittcustomaudiocables.comHe has great quality, a big variety and you can get really nice cables for less than buying from many other companies. I particularly like the Interconnects made with vintage Western Electric Wire from the 40’s & 50’s, they provide a nice warm smooth sound.
just some thoughts, happy hunting!
