Master Clock for your EtherREGEN

[_JL_]

Two is Not Better Than One!

 

So I have two clocks, one CyberShaft and one Mutec. Have been using the Mutec for the ER for some time. The Cybershaft was powered (to keep it warmed up and stabilized) but otherwise sitting idle unconnected.

 

The other day I accidentally disconnected the power to the Cybershaft and noticed a jump in audio clarity - basically the proverbial veil being lifted kind of thing. Initially I was not aware of the real cause and just attributed it to less AC noise on Sunday. But later after carefully tracing the wiring I realized that the reason is due to powering down the Cybershaft. The veil would return if I power up the Cybershaft again.

 

This suggests that the idling Cybershaft is somehow interfering with the system, causing the degradation in sound quality. The Cybershaft is sitting atop the Mutec with its output unconnected so I guess that contributes to the interference. This also cast questions on tests comparing multiple clocks as they may in fact interfere with one another when powered on simultaneously.

 

If you have more than one clock you may want to experiment with this, just in case.

You sure don't want a component placed right over a different component. Of course, there could be more to it.

 

True but I ran out of rack space long time ago so no choice for now. The CyberShaft is on top of the Mutec even when not powered so the difference is not due to stacking.

Mutec is particular about their steel enclosure, because of possible disturbances. What is the Cybershaft enclosure made of, aluminium?

The Cybershaft enclosure is made of aluminum I believe. It's much lighter than the Mutec FWIW.

Which Mutec do you have and what do you think of it? Sound quality of Mutec vs Cybershaft?

I have the Mutec SE120 and the CyberShaft is OP17. I compared them quite some time ago (was waiting for the Cybershaft to run-in). The main difference at the time was in clarity, i.e., resolution, transparency and air. This is probably not a fair comparison as the Mutec is 3x more expensive.

Hi guys! Sorry for the off-topic as this thread is focused on etherRegen, but as I have read some of you are using the Mutec MC3+USB with an external 10Mhz clock, I just wanted to know if the internal jumper JP1 in the MC3+USB has to be changed from the default manufacturer position "2" (75 ohm termination) to "1" (no termination) to connect an external clock.

My clock is Giesemann Double Crown.

 

Thank you very much in advance!. Any help will be appreciated!

 

Best,

I don't think the jumper needs to be changed. It should be terminated at the MC3+ unless you're daisy chaining the clock to other devices (at which point only one should be terminated).
