My sub cable length is pretty long, about 30 ft, and there's a slight hum. The DAC feeding it has balanced and RCA outs, but Sub only has RCA input so that's what I'm using. Presumably a balanced interconnect would improve matters. Any thought on the best way to convert?? Transformer? One of the small active devices using opamps or whatever? Other? Comments welcome, thanks in advance.
