Does anyone know if there is a device that can upscale the audio quality of mp3s like the x-mod. I have a Roku Soundbridge connected to my home theatre system, and was wondering if there is anything that I could put between the Roku and my receiver (preferably with digital in and out)to improve sound quality of my streaming music? The Roku sounds great, but there is always room for improvement. Any info or recommendations would be greatly appreciated. Thanks!
