Review on Tripp Lite LC2400 Conditioner Outlet by Adam Rossi

I wanted to like this device. It's built strong. I can't say for sure if the line noise has improved, but I have another problem. I got this power supply to set up power in my project music studio, but when I turned it on I quickly noticed a rather loud coil noise. from the unit itself. I didn't notice any hum on my lines, but since I got this in my studio for noise reasons, that's a moot point. I've had it for about a month now, I'm hoping the hum will magically dissipate, but at least it's gotten louder. I see other reviews saying this unit is quiet for them, but mine has an annoying coil whine. I'll contact support and see what they say.
