Separating cables, is there a mat to help along the way?


I'm trying to tackle separating my power cables from speaker and interconnects and ethernet/hdmi video and other cables  from each other. I will do the best I can behind my TV/console area but also wanted to use some kind of shielding if it is available for places I can't keep them far enough away. It's a bit tight back there but I do have verticle space which I may want to build a quasi shelf to hang cables on/from..  I figured if I could get them far enough away from each other and use something to wrap the rest of the cables so they would be separated that way.

Maybe even tape or something that would help, but I would hate to "ruin" my expensive cables with tape, but not out of the question if it would work, as I plan to keep my current cables permanently. 

I'm also planning on replacing all wall warts with some kind of lps to reduce unwanted noise even more. I'll plan on running those new cables away from the current ones I have now. Just planning for future upgrades now, with possibly Sbooster or  Uptone Js2 or something.  I've had a mess of cables behind my equipment for a while and have decided to clean it up.

Any ideas about the shielded mat or tape or covers?

Thanks for reading.

I am having noise problems, but also it was a huge mess back there. I've since cleaned it up a lot, so I'm still going. I go through spurts of upgrading, then I stop for a while. So I'm striking while I'm in the mood I guess. I'm sort of working backwards with upgrading.

I just bought a couple of Niagara 1200 power conditioners (one still backordered) and ran a dedicated 10-2 line for everything. Installed a Furutech receptacle. Finishing the full loom of Cerious Matrix cables, that I started last year. 

Looking at the lps to replace all the  wall warts and some kind of preamp or integrated to finish off everything.

Right now its cleaning up the bird's nest of cables, but it doesn't look promising because I have to work vertically as my components are low to the ground and bunched up together. I'm sure whatever I do will be an improvement. 

Thanks for all the replies.
If you want to replace SMPS, Teddy Pardo is your friend. Most values ready made. FAST delivery from Israel. Best bang for buck. Although for 5V 3A the Allo Shanti is a steal.
Looking at Sbooster and Uptone mostly, but still researching, and again, going backwards in terms of my approach. I just bought an EtherREGEN and going from there. Just going into a Bluesound node for now. 

Will look into Pardo, Thanks.
Might want to try rubber pipe insulation to separate them where they touch , you can cut in it the length you need, I use it at certain points behind my rack where the ICs and power cords are right next to each other . I put a piece around a portion of the PC where I need it . Comes in different sizes but the link below shows the insulation. You can get it at most hardware stores. Aside from that I use wood  cable elevators to keep cables off the floor
