Hi-res from Pandora will probably not happen any time soon. With your Sonos however, it is possible to both upsample to 24/96 or higher and reclock to reduce jitter. A good reclocker can do this without requiring any mods to the Sonos. Upsampling often makes the DAC sound a lot better because it utilizes a less severe digital filter inside. Reduction of jitter from the Sonos will revive the soundstage and imaging, as well as improve the dynamics.
