Upgrade speaker or analog source?

I need help on deciding which part I should upgrade.
My setup is
Rega P3 with Denon DL110
CJ Pv-10B w/phono
CJ Premier 11A
Proac Response 1SC

Which part do you think I should upgrade to have the biggest impact on sound quality (mosly used to listen to jazz/vocal).

My budget is 1500-2000.
Right now I'm thinking to upgrade to either Michell gyrodec (I have rb300 with incognito wiring) or proac 2.5.

Or another option is upgrade denon 110 and phono amps/preamp

What do you guys think?

Thanks

Edwin
