Living audio set-up

Hi you all,

I want to upgrade my audio set-up (from a very basic with and old Pioneer amp and Polk speakers) and I have $8,500 to spend. I want to start choosing the speakers, but would also match them with an amp and a preamp. Some references:

- I used to listen to music with my turntable and my computer.
- I mostly like jazz and classical music.
- My living room size: 20x10 ft.

Would appreciate any help, considering some limitations: I'm from Chile and only some speakers could be found here (Revel, KEF, ATC, Harbeth, Dali)

Thanks :)
