I'm no expert, but come on guys. Is Electrical grade porcelain really needed for the amount of electricity we're talking about??? I use clear plastic coctail cups turned upside-down with a little channel cut into them. Works fine. Total cost: $2 and 20 minutes. They're virtually invisible. I own some expensive cables and components, 1 aftermarket power cord, and some other tweeks, but this IS where you draw the line. If you want to spend $80 on the cool looking (admittedly) Audionut type cable towers, do it, by all means, But you will hear no greater difference than if you were using my plastic cups, or using Nylon line to suspend them from the cieling. Buy some music instead.
