Clocking: again!

@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.

You do indeed live in a DSP controlled bubble 😂

Guilty.

was impressed both by the sound quality and the quality of engineering exhibited by the Dutch & Dutch 8c. Even without REW, the 8c's response extends at full level to 20Hz. But with the REW integration and the ability for a pair of these speakers to act as a Roon endpoint, which will be available by the time you read these words (footnote 5), I echo Kal's conclusion that the D&D 8c demonstrates that active, DSP-empowered speakers are the future. And I also echo what I wrote in our original review: "Wow!"—John Atkinson

So I have the Etherregen and love it.  Precisely which 10Mhz Master clock is recommended with it and whose cables?

@dougthebiker  Hi Doug, This is what the manufacturer says and to be honest clocking the Etherregen alone, I doubt is going to produce such a big change as clocking your streamer and/or DAC together with the Etherregen.

Extreme usage with an External Reference Clock:

The Crystek CCHD-575 oscillator used in the EtherREGEN is one of the lowest phase-noise production crystal oscillators (XO) available. [Sorry, but the $50~$100 OCXOs we see tossed into stock switches do not outperform the Crystek at low-offsets where it counts; Manufacturers have to spend $500 and up to obtain OCXO clocks with significantly lower phase-noise than the Crystek we use.]

Yet some audiophiles have discovered benefits using expensive ultra-low-jitter/low-phase-noise 10MHz reference clocks with their DACs or USB streamers and conditioners. A clock synthesizer (to generate the various frequencies) is always required for a device to accept an external reference clock. Since we already utilize a very advanced one to produce the 4 clock lines in the EtherREGEN, it was easy for us to include provision for connection of an external 10MHz clock. The BNC jack and termination resistor of the EtherREGEN are for a 75ohm clock line. (We can provide units with 50ohm, but only upon special request.)
