Electrical outlet upgrade worth it?


I live in an apartment. I am currently working on purchasing PC's and conditioners/filters. Question is:

I do not have a dedicated circuit nor do I want to put one in at the apartment. As such, would upgrading the outlet which my audio goes into be beneficial or a waste of $$$?

Thnx,

Thank-you Lak, I had not read your Hubble Cryoed vs. Wattgate. I have now, and well written too.
Yes just do it. Hubbels are good, Acme is better. Heck the Pass and Seymour $5 outlets are good too. Anything is better than the cheapo outlets everyone has.
