Where should I start upgrading?


Today I have a THORENS TD 160 B MK11 with SME series III with Nagaoka MP-110 cartridge.
Phono Stage Primare R32 with both MM-MC.
Amplifier Accuphase E-206
Speaker cables Transparent Music Wave Plus.
Speaker Wilson Audio Cube (First Model)
Sub REL T3

What should I start updating to get the most value for money?
For about $ 1000?
2000 dollars?
$ 3000?
Listening to everything from Gregory Porter to Led Zeppelin and Leonard Cohen

1. put the turntable in another room for acoustic isolation
2. get the pre- preamp and put it as close to the turntable as possible with a short cable run, then run longer cables to the preamp or receiver
3. room treatments & moving speakers around to optimise the room effects 
4. new speakers
It looks like that 8 inch subwoofer might be a weak link in your system. It would be a good start to replace it with a 10 or 12 inch sealed type . Take a look at these!

Looks like it should sound good. What do you want to change in terms of the sound?
