Help me build a $2,500 system

So, as a budget Audiophiliac, I’m looking to take the next step up the stairs. My budget is $2,500 but I’m thinking I will keep two of my current set up’s pieces, unless swayed otherwise, my Onkyo C-7030 CD player and Musical Fidelity V-90 DAC. 

I’m not opposed to completely restored vintage stuff or brand new. I just want the absolute best sounding set up I can have. 

My room is open to the rest of the downstairs and is roughly 15X15. 

I listen to mostly rock at low to medium volumes. I’m a stickler for well produced stuff and stream lossless as well as listen to well recorded CD’s and will choose my vinyl carefully as well. 

I’m looking for:

Amp/Receiver

Turntable (leaning hard to Pro-Ject Debut)

Speakers (prefer floors)

Cables

So, go to it and give me your best suggestions!  I greatly appreciate all input and opinions. 

Thanks all. 😊
