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 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. 
My 2 cents:
Remove the stove from the line.
Install a whole house surge protector. They're cheap.
Add an additional outlet/s for the mono amps.
Buy a used Audioquest Niagra 1200 for your sources.

I agree with Erik on the room treatment. It is a very much required investment for a system to really shine, regardless of connector thingies.
I think my problem is a lack of understanding of basic electrical knowledge. Last thing I want to do is take any power away from the subs or equipment. Im not really trying to tweak anything yet... I just wanna get everything plugged in properly and make sure all equipment is getting the power it needs without roadblocks and distributed evenly..
I ordered a few pwr cords from Cullen Cables and its going to be a couple more weeks till they get made and shipped so i have time.. I suppose anything will do. Room treatment is pretty much the only thing I see people agree on and am looking forward to diving into it.
