Advice needed for analog upgrade


I want to upgrade my analog rig, but I'm not sure what to tackle first. I'm using a Rega P5 turntable, Dynavector 10x5 cartridge and Dynavector P75 phono preamp. What component upgrade would make the biggest improvement for me? Thanks.

budget? 
If it's big, turntable will could make a big improvement. For a smaller amount, could be cartridge. That model barely scratches the surface (see what I did there?) of Dyna house sound. P75 is pretty capable and likely fine with whatever you step up to.
Be sure to consider cartridge/tonearm matching and cartridge output/P75 gain matching to ensure a good result. If that's over your head read the archives on MANY similar discussions and use the vinylengine calculator to help you achieve an optimal resonance frequency from you cart/arm combo. 
This best component in the world won't sound good if you mismatch either of those two relationships. Cheers,
