Ever notice this? Less and less electronic devices are offering toslink connectivity or are limiting implementation for this connection, especially in the lower end market. Just a few years ago most receivers had an overwhelmingly dominant amount of toslink connections, now you look at the back your your average Onkyo receiver 5 years ago, and look at one now.
Same with Sony. My Sony STR-DA1000ES has 4 optical inputs and one coax, the new ones have at least half of the digital inputs dedicated to both.
