I am actually going with AfterDark, i just need to know if it should be the 50 or 75 sin or square. Here is the spec on the DAC “ Support of external 10MHz clock input (default is 50 ohms) “

You dac is 50-ohm unless custom - ordered. Square is indeed best but you need a good cable.

I am super new to Clocks so this is helpful. out of curiosity is 50 less than 75 for quality or does ohms not equal quality?

The impedance depends on the device to which you connect the clock. Your DAC has a 50 ohms input.

Cable impedance needs to be matched with the gears. All 50 or all 75. Good and affordable 50-ohm are rare. Some believe 50-ohm is best for clock transmission but with an excellent cable, either will do. I mentioned the two best choices for reasonable money. Just get the Concentus, it is worth it.

Did you already order it? If not, you can still choose 50 or 75 Ohm. Does not matter in terms of quality I believe. My experience is that it is easier to find 50 Ohm cables.

He already has the dac, which is 50-ohm.

Either the lhy ock2 or the new affordable mutec. The ock2 is the bang for the buck on paper. Many satisfied customers. Best price on aliexpress.

Most sellers on Aliexpress have the LHY OCK-2 for $530-$560, but Fook Key Electronics has it for $281 (all + ~$50 shipping). Any idea if they're legit?

Likely not. Some links on ali can be traps. This clock is a great bargain for around 550.

I think you may have selected the OCK 1 instead of OCK 2. The OCK 1 sells around $400 and OCK 2 around $700

Indeed. Must be it.

The license is hardware related.
You can buy a lifetime for your streamer or subscribe for a year.
This is the basic package that is already excellent. And you can improve it further with additional options.

Have you tried RopieeeXL ? (I prefer it to PiCorePlayer…)

Ropieee has a limited purpose. It's only an endpoint to which you can stream from a server running a different OS.
I know Ropiee of course. It's a good distribution, and I used it during a few days last month. I did it in a streaming setup that was a bit complex in order to use Gmediarender as a renderer for Roon.
Roon was running on my Mac, Ropieee was the endpoint, and it used Gmediarender from the GenntooPlayer Host.

A few days layer, I found how to do the same without Ropieee, and with the better SQ of the Diretta protocol.
I'm still using Gmediarender as a renderer for Roon, but I do it with the GentooPlayer setup.

No, this listing shows the OCK-2 for $281 and has a $25 coupon.

Select the last choice to the right for the ock2. 530usd before coupon.

I have a AfterDark "Queen," 50 Ohm Sinewave clock on order.

I am looking to get the benefit of an external clock in my setup but am confused to where I can or should connect the clock.

Both my streamer (Hifi Rose RS130) and my DAC (Audio-GD R-7HEMK3) have internal clock inputs. The 50 Ohms is required per the DAC. I connect both devices via i2s. So where should I put the clock. On the DAC or the Streamer? I am a bit confuse why the streamer would even have a external clock input as I would think the signal would be negated once in reached the DAC?

The internal clock of the RS130 is actually pretty good as it is a OCXO clock but it is not used or should I say, "overridden," by the internal clock of the DAC if I am understanding things correct. Why even put a external clock on a streamer only since there is no DAC, won't the connected DAC always become the primary clock regardless if the DAC is using it's internal clock or connected external clock?

My assumption is that I should connect the external clock to the DAC and still use the i2s to i2s connection of the two devices. Please correct me if I am wrong.

Thank you in advance.
