So as my signal chain becomes better I'm now noticing how dirty the noise floor is in my studio. Especially when I need to record more delicate tracks such as acoustic guitar and vocals.
The studio was inherited and the built in snakes are likely to be 20 years old. The main power supply is single phase and runs all the power outlets in the building. I'm no building expert, it's possible that this could be running the lighting too?
I've learned enough to know that improvements are usually a sum of parts as opposed to a single magic solution. So I guess my question is to ask what you guys have done to help 'clean up' your supplies and minimize noise floors in your systems. Does making changes to the power supply help with noise floor issues? Does old cabling degrade in quality over time?

The only thing I'd be worried about with 20 year old cables is the ends. If there are cold solder joints or bad punchdowns (depending on how it was wired) they could be a point of weakness in the system. It's also a place where you can have a hole in your shielding if the installer wasn't meticulous.
But really, by "single phase" you mean, essentially, the building was wired with 120v power, not 240 (or whatever voltages they run in the UK?) where you can put the lights, fridge, a/c, etc, etc. on one leg and your studio on the other? In that case, it sounds like you'd be an ideal candidate for one of those power isolation transformer thingies.
