Clocking: again!


There are all manner of folk claiming that clocking is irrelevant to Ethernet and USB connections. While this is obviously ignorant of the RMI/EMI and ground level effects on DA conversion and the analogue stages of a DAC, the level to which digital clocking matters was again brought into stark relief when I changed the clock cable between the Antelope 10m clock and the Etherregen from the cable supplied by Antelope to a Shunyata Clock75 Sigma cable. Shazam! Everything jumping into focus and significantly more snap and reverb. In our hobby everything matters and we are only at the very beginning of optimizing streaming.

There are 3 factors involved here;

I. Master Clocks 10 Mhz 75 or 50 Ohm

2.Word Clocks which have to be manually switched to the frequency of the source recording e.g. 44.1, 48, 192 kHz etc.

3.Re-Clockers which reprocess and de-jitter a signal between the source and DAC. A re-clocker usually benefits from a stable signal from a Master Clock.

A clock without a linear and preferably regulated DC power supply is like a ship on the high seas, whereas a good power supply brings it onto dry land.

Imagine your family all used different clocks no one would get to school/work/whatever on time. All your digital equipment connected to the same Master Clock keeps everything in synch.

Yeah, those DSP controlled active speakers with the built in DAC are junk, I wouldn’t recommend them to anyone here unless they’re interested in state of the art design, FR and sound reproduction. Of course you'll need to find somewhere to introduce a useless clock. 

“state of the art design, FR and sound reproduction.”

You do indeed live in a DSP controlled bubble 😂

@lordmelton  has the solution on clocks. So, the question becomes in what order do we upgrade streaming solutions. We have the choice to optimize clocks first, or after server, streamer and all other network upgrades available to us.

@sns If you're using computer audio your first priority should be a re-clocker. If you have a streamer then a Master Clock but it all depends if these devices have a clock input.

If you PM your personal case maybe I can assist.
