I did confirm that all my IEM's and Over Ear work fine with the Magni. You are probably right that it is damaged. They sound fine at medium volumes and below. What are the signs of a bad cable (The cable has no signs of wear or tears)? Replacing the cable or doing detachable cable mod doesn't seem too expensive. But replacing the drivers seem pretty costly... might as well buy a brand new one. Do you know the cheapest place for replacement drivers? Thanks.
