"Digital audio is the art of time, with our new proprietary clock design we have managed jitter rates of unrivalled 100 Femtoseconds, this easily outperforms many renowned and respected audiophile clock generators!"
Remember when Bryston's 1st DAC had only 1 nanosecond of jitter? Nowadays good digital is under 100pS, while expensive jitter removing gadgets give <20pS.
This little guy claims jitter <100fS, 20x less. Not sure if that's under all playback scenarios, but that, combined with high resolution tracks should be quite a nice sound.
The output stage is yet to be discovered, but it's probably more than adequate. There's some nice sounding opamps available now.
