If it’s stereo as you say, and you have no RCA outs you can use, the easiest is probably optical, then HDMI. Any old audio extractor that outputs to RCA should do the trick, then each of those RCAs into its own amplifier. HDMI option will only work if using an ARC port of your TV (some HDMI ports should say ARC, audio-return-channel). If you don’t care about using your TV for broadcasted content etc, and are just using it as a display, e.g. you have a device outputting hdmi into your tv, there are splitters that intercept the signal rather than you having to use the arc port on your TV.
