Very Limited Space/Wall Outlet

I have a small problem. Building my first system.  In that system is a intergrated amp, power amp (running mono mode), two sub woofers, turntable, phono pre amp, cd player, dac. 8 to plug in. But only one outlet. It's a 20 amp circuit...but has a 15amp receptacle. The only other item on that line(as far as I can tell from turning it off) is the gas stove. Right now I only have one amp and my turntable plugged in and have had 0 problems. Waiting on a couple power cords to arrive then will be putting the pieces together. So, I obviously need more outlets. What am I getting? Am I getting a power strip, power distributor, power conditioner, surge protector or combination of the bunch? I live just outside of Detroit, so power hasn't been much of a issue. I've read somewhere to not have analog and digital plugged into the same outlet...so..if I can somehow find a way to plug the DAC into another circuit I should be good on noise. I also don't know how these work...I always assumed everything plugged into a strip gets the power it wants. I spent a lot of time researching gear (iota vx sa3 and pa3...rel t5i subs) and would hate to cause those devices to not be at their full potential and not know it. If all I need to do is STFU and get a surge protector then don't be shy...let me know. I tend to over think things. Thank you.
