Importance of clocking


There is a lot of talk that external clocks because of the distance to the processor don‘t work. This is the opposite of my experience. While I had used an external Antelope rubidium clock,on my Etherregen and Zodiac Platinum Dac, I have now added a Lhy Audio UIP clocked by the same Antelope Clock to reclock the USB stream emanating from the InnuOS Zenith MkIII. The resultant increase in soundstage depth, attack an decay and overall transparency isn‘t subtle. While there seems to be lots of focus on cables, accurate clocking throughout the chain seems still deemed unnecessary. I don‘t understand InnuOS‘ selling separate reclockers for USB and Ethernet without synchronising Ethernet input, DAC conversion and USB output.

Streamer onwards we want a clock, external or internal, which is very low noise and very accurate.

Up to the streamer we merely want a clock, external or internal, which is very low noise.

I may not be arguing, but I sure as hell will not be buying any of his products.

I believe accuracy, short-term stability and phase noise performance are equally important in a clock for optimal sound quality.  

@lalitk Could you explain why the accuracy of the clock (which is defined by the long term stability in ppm) is as important? Genuine question.  For example the most accurate clock that I know of is cesium atomic clock which is approximately 1 -  3 part in 10^14. Is it relevant, does it matter for HiFi?
