With some sort of converter box at end to send real signal to speakers.

These are analogue readers rather than transmitters, but may be of interest.

Think I did this in the 80's with a radioshack 200in one kit just aim an incandescent bulb at a photodetector :D

Pretty sure you could transmit DSD as is like this too... problem is it'll sound like ass :D

They went digital over mediums like this (light, radio (RF wireless), etc) to avoid all the variability :)

-- great example are wireless speakers..... 10 years ago, it was analog over wireless and *always* sucked.

@Scott Kramer All those transit the signal though air though. What about transmitting it through a fiber optic cable? I might try to do something like that some time, just for fun.

Dunno... sounds like a fun project. Will probably come down to the receiver precision. It is 2 extra unneeded optical to electrical conversions tho... ;)

What about the AT&T inputs on vintage DACs? Is that anything like what you're asking?

I tried to once but I ended up traveling into the future instead.

@Northwest What is that? Any links to info on that?

I know almost nothing other than it isn't Toslink. I first read about it here. http://www.superbestaudiofriends.org/index.php?threads/marveys-dac-chart-of-awesomeness.63/

I see these connectors on SFD, and Theta products.

If you ever take a class in digital communications you can use this as a project (depending on how strict your professors are).
