Since my studio gear has gotten some additions (new synth etc.) I'm running into power issues. First of all I get a hint of 6,5kHz (+harmonics) on the instrument input of my RME Fireface UC. Second I'm running out of AC outlets :)
So I looked into getting a Power Conditioner. There are several brands and different levels of 'conditioning'. Furman seems to be the 'standard' but I also saw a new product called Nusonic Powerplant.
What are your experiences with these devices? Do you really need 'digital filtered' outputs and 'analog filtered' outputs? Or can you simply buy 2 separate devices for digital and analog stuff?
Not an electronic engineering expert so please be gentle :)
