Just wondering if anyone knows of a worthy ground loop isolator. My power wires are nice and friendly with my RCA's, and although I will hopefully fix it properly this summer, right now I just want to get rid of the dreaded hum.

I like the price of this one, but I'm guessing you get what you pay for...

Anyone know if it's decent? Or recommend another one?

Also it is only for my speakers, so I don't think I have to worry a whole lot about it cutting out the low frequencies (which I've heard is a problem on the lower priced ones). I'm not going to put one on the subs...

Thanks!
