What should I upgrade first amp or preamp?


I need your help. I have OPPO BDP-105 connected to PASS Labs XP-10 and XA-30.5 driving 89 dB at 4 Ohm Snell C7. Looking to upgrade my system and planning to spend $ 3000-4000. I live in the apartment building and unfortunately can't listen to music very loud (no more than 58-62 on the XP-10 display).
What would you suggest to do, upgrade preamp to XP-20 first or amp to two XA-60.5 or to XA-100.5 and why. Upgrading an amp is more problematic due to the space constrains.
What will I gain and what should be the difference in sound in each of those cases?
Thank you.

Why not upgrade power cords and add power conditioner which will be far cheaper than adding new component.
arapuz couple of more insights...

Upgrade to Analysis Plus new black oval 9 or silver oval 2 improving detail and bass $550 - $900.

Living in apartment, I would seriously look into Power Conditioner. Condition the AC may significantly lower the background noise which is probably on the same line as that contractor grade refrigerator $2000

Lastly, the right power cord may provide more detail and clarity depending on overall designs for both amp, preamp and source. And you can borrow the cables from the Cable Co cable library to help make your decision.
