How do I feed Internet Radio to my rig?

I am a novice on this stuff. I am currently feeding a digital signal from my Panasonic HD recorder to my Esoteric K 01 DAC to my rig. The Panasonic is connected wirelessly to my router. Sounds great but there are a few problems. It uses Shoutcast for internet radio which seems to have a smaller selection of radio stations than I am used to. You also have to turn on the tv monitor to see what you are doing. The analogue outs are awful and it would be nice not to have to run the K01 every time (but not a big issue though). What are the options for high quality Internet Radio feed? A stand alone unit? Laptop? iPhone? etc
