How do you send an internet stream into a hi fi?


Wondering how to take a radio station stream or other internet-based music feed and run it through either my Rega Mira3 or my 1971-ish Sansui AU999 amp? Thanks!

I use the Outlaw Audio OAW3 wireless system to stream internet radio to my 2 channel system. I think the only issue is I'm at the mercy of my laptop's DAC. I'm not sure though.
I use a Musical Fidelity V-Link which is cheap (<$200), and easy to use. It converts the USB output on my laptop into SPDIF. I plug it into a digital input on my CDP and it just plays. Works good for iTunes. I imagine it would work ok for digital radio as well.
