That's strange that Epiphany does not ground it. Are you sure? there's a couple ways to do that, JDS uses the default method, wire to front panel screw, but you can run the wire to the back panel as well. It's pretty easy to do it yourself if nothing else. But a strange ommision on their part. Though, it may not have any real effect on sound quality.
