Got a pair of Eris E8s two years ago, and I've been really satisfied with them since.
I recently moved from the countryside to a city, and when I turn them on now (even without anything connected except the power cord) I get a terrible hissing sound, which makes them useless for listening to quiet sounds.
I could lower the noise pretty much by wrapping the speakers in aluminum foil, but I don't really fancy the new look and the noise is still too prominent.
Can I do anything else except wrapping the entire room in foil?
