Cable management....crossing at right angles or

Unfortunately, same with me. I get the speaker cables out and on elevators… and generally I can separate the interconnect to my amp in front. But the audio racks have a rats nest.

I am sure it is in that category of tiny difference. But one you should avoid if you can. Tiny differences add up. But unless you have a huge room and lots of money (to buy extra lengths to allow crossing at right angles)… it will probably remain on one’s wish list.

Iv’e not heard of wraps or special tweats. But great question. One of the tweakers must have experimented. I look forward to hearing.

Your cables should be shielded, so positioning isn't as critical as say- two wires with just insulation being crossed.

A rats nest of wires with no discernible pattern. 

Rat's nests are very underrated/under appreciated. They serve a vital purpose.

All the best,

Try these, I found them to be quite effective in isolating IC from PC cables.

You are worrying too much about this! there is a difference between being neat and being obsessive for no reason, unless of course you are having a problem that you have not mentioned. Take the lid of your pre-amplifire and look inside for some aspiration. There are a number of steps you can take to untangle the mess but I think you already know what to do!
