1st time AG'er. Cables ? ?

.
Thanks to all who responded. I'd gone a little wacko trying to sort thru the strings on IC's,etc. - just needed some focus. Much appreciated. I'll explore all these suggestions thru AG and the links provided.

To Dave: the dedicated 20 amp line is no problem. As my son went off to college I've taken over a 22' x 24' room with main breaker panel. I can add a branch circuit with a single outlet that's within 8' of amp.

STOP! My first suggestion is find some really low priced ’good enough to get by’ cables all around.Blue Jean cables are a possible choice. Cables made with Mogami wire, Canare Ok too. Cheap is the word. Any cables you can scrounge up for free? GREAT!!
Get to KNOW you equipment. Listen to it. get to enjoy it before jumping into the madness of aftermarket cables.
If you think, Jeesh I want more from this sound.. THEN yeah, start looking. Not now.
After a few months (really!) after awhile then decide which area you think you might be interested in.
A power cord, or IC, or speaker cables? (Seriously using a good ordinary cut up extension cord can work GREAT Cheap, and good enough for a long time. really $15...) I have $$$$ system, and have used eBay 0$0.30 ft wire for my speakers. Works great, sound pretty good.
For the wall duplex? Pass & Seymour heavy duty 20 amp $4.99 https://www.amazon.com/Pass-Seymour-Specification-Heavy-Duty-Receptacle/dp/B008SBH18M/ref=sr_1_6?ie=...or for a lot more money and a tiny maybe gain: Hubble $25 https://www.amazon.com/Hubbell-HBL5362W-Duplex-Receptacle-Industrial/dp/B000LE6N56/ref=pd_day0_hl_32...
Anyway, good luck.

Good advice Elizabeth, you're a little late on the response though :-) 

great purchase you made. my opinion after going through tons of high end cables; i have found audioquest perfect silver surface cables such as niagara to be smooth, detailed and extremely musical. they are discontinued but virtually indistinguishable from the replacement model(wind). i find they give ss equipment a little more lushness. i’d match to aq speaker cables using their highest grade copper. several to choose from. your equipment deserves this quality of cable. copper just can’t do what pss can. finally buy used of course and don’t go funky with garage brands. aq knows what they are doing. 

Best advice is that given by elizabeth.  Get everything dialed in, then fine-tune with cables.
