Anyway looping a cord like this is a recipe for noise pickup and will always sound worse than leaving the cord loosely draped and ideally away from power cords (or crossing at 90 degrees if needed). This is one of those cases where neat is definitely to be avoided. Anyway I'm sure you've already noticed this and fixed it but just wanted to be sure especially as you have had some concerns with noise in your setup. I know from experience that cable dressing really matters as just last week I induced bad hum in my phono stage from having the input interconnects from my tonearm running too close to a power cord, drove me nuts until I spotted it!
