What component to upgrade next?

Looking to upgrade a major component. Budget ~5k. 
Here’s my current set up. Listen to 50/50 vinyl/digital.

Parasound P5
Parasouund A21
Revel F208s + Gaia 2s
Project DC Carbon + Isoacoustics Delos
Chord Cutest DAC
Bluesound node 2i
Nordost Blue Heaven interconnects for everything
Nordost Hemidal power cables
Isotek power conditioner

Open to ideas for minor upgrades as well. 

Thanks!
