Hey, I need to put an order through in a few minutes for a Furman power conditioner. I've used the Classic line before and would go that route, but I'm wondering if I can go with a Merit X series for my application and save $125. It's just for a recording booth, currently using a wireless Sennheiser going into a ZED-10 mixer hooked up to a Kona LHi. I'm not really concerned about the surge protection as much as I am getting a clean AC signal. For vocals (voice overs only), do I really need Linear filtering?
