Spaghetti cabling behind entertainment center

The only locking plugs I use are for my speakers, as I have real 8 awg speaker wire, I needed bananas to fit the 7mm wire and 9mm jacket.  I use those nakamichi cheapo ones.  No, they don't get picked up by my magnet, so they're not made of iron. 

Anyway, when the preamp comes Thursday night, I will reroute all my cables, and keep the power cords separated from the rest.   Thank you guys, much appreciated!!!!!!!   !!! !!!!!

Keep power and digital cables as physically separated from other wires as possible, especially anything running from a phono.  Use shielded ICs if in doubt.   Plug power amp units directly into wall, no power conditioner, separate outlets from others if possible.  Separate circuits even better if possible.   Use good quality power cables designed to shield noise with digital devices in particular.  Can only help with pre-amp and power amps as well.  

As far as keeping cables off the rug or floor, I've done that but notice no change.  I'm not saying there isn't one, just that it doesn't matter to my ears.  Try it yourself.  Use paper cups, or something like that to lift the cables and see if you hear a difference.  I use small wooden dowels with a wire tie to hold them together in a tripod fashion to lift cables over others.  Now that I think about it, I still have those ceramic insulators.
