RE: Possible to split a 10Mhz clock output?

The subject of using external or system clocks is more complex than finding a stable generator for the signal. The whole subject is way beyond my competence but I understand that issues such as phase behaviour and the PLL for distribution are important.

All dCS system clocks have multiple outputs so what you want to do is achievable. However they use " low noise, low skew clock distribution systems that get the clock to the point of use exactly as it was generated." - whatever this entails.

What is subjectively observable is that dithering the signal seems to improve the distribution (apparently has something to do with " dead spots" occuring in regard to the PLL). It is switchable on/off with their clocks so comparison is simple.

I have also experienced the significant changes in sound that comparing different generations of their clocks brings even though basic clock stability specifications are similar.

Unfortunately the choice of 75 ohm cable seems also to affect the resulting sound even given cables claimimg quite tight observance of the spec and with due attention paid to screening and using "audiophile approved" dialectrics such as PTFE.

I have also seen arguments from pro recording engineers that the use system clocks is worse then just letting each component run with its own inbuilt clock. I don't necessarily agree but the argument is out there.

So, as the subject itself is not very straightforward it is hard to guess whether BNC splitters are "good" enough for hi-fi.

Suck it and see. If you are happy with the result then that is what counts.
