Let's expect the ultimate portable MP3 player with atomic clock reference... >:]

Also funny are the offerings with RbO CD-clocks... usually "tweaked" FE-5680s, which are not exactly famous for a clean jitter/spurious free output signal... The only reason is the easiness of output frequency adjustment (for the DDS models) to that of the standard CD clock, which promptly places a premium on the price tag. A good XO is way better and cheaper, with the notable exception of temperature, and long term stability - still waiting for the golden ears capable of hearing that one...

Well.. there is lots of bogus information going around in the audiophile
scene... Probably mostly because todays audio technology is so advanced,
that Clarke's 3rd Law applies...

But to bring this back to time nutty topics, have a look at
http://www.colorfly.eu/product.html
It's an MP3 player with high precision timing. It does not only use
two TCXOs with<5ps Jitter.. No! It also employes a technique known
as "Jitter Kill" for the ultimate mobile sound experience! :-)
