People: choose your sides, and ....
go!
I downgraded my ethernet cable. I had installed Cat6 but got all kinds of interference problems caused by the shielding. This was especially problematic with my headphone amplifier, even the electric shower caused interference. Changing to Cat 5e sorted the problem. So my recommendation would be to make sure you don't buy any shielded ethernet cable.
