Transporter - Background hiss


Just bought a logitech transporter - its hooked up using analogue outputs to my Arcam AVR 600. I'm getting a lot more background noise/hiss as opposed to my CD player (Arcam CD17) when the device is idle. I've changed the cable and the power cord but the problem continues. Should I be using the digital output instead ? Thanks in advance for any suggestions.

Problem solved ! Turns out it was the"upgraded" power cord after all - I went back to the stock kettle lead that came with the box and the hiss went away.
