Master Clock Talk

Are there any measurements of the Afterdark "Emperor Double Crown" master clock?
AfterDark publish for the Emperor Double Crown -117dB @1Hz noise. They always include a noise test plot with the clock.
This compares with -118dB for my Triple Crown.

Interestingly, I also have an AfterDark King which claims -107dB and it does not sound as good as the internal clock in the LHY SW6. So the LHY is at least -108dB or better. Their claim of -110dB seems reasonable.

I am currently using a Belden, but the 4694R. I would like to try "audiophile" matrix cables. I am hesitant between the Neotech NEVD 1001 and the Oyaide BC510. I am not sure if they will improve the sound, but they are 100% silver conductor cables and will surely change it.

P.S. I'm actually also evaluating other cables like the Audiolund Xstreme (Duelund copper), the Kiber D60 Illumination and the Furutech FX-Alpha-Ag
I see that “4694R” is a type with a center conductor of 1.02 mm.

I tried various lengths and thicknesses, but the “thick” and “short” types gave relatively good results.

The clock cable I now use is a Tubulus Concentus silver, which sounds marvellous and is a considerable step above Belden 4694R (which itself is a good cable).

Or the cable & something else like noise cause worse sound even with better external clocking

It's the same Tubulus Concentus as I use with my AfterDark Emperor Triple Crown that I use with my DDC and that sounds superb.

I was surprised by the LHY outperforming the King, but I'm fairly confident the comparison was a fair one.

This is the super LHY-2S clock, not bad at -116.8@1hz

I think you can organize international direct shipping now from Taobao, not that I’ve done it. There’s also the default freight forwarding agents I assume. All a bit more of a faff than AliX.

@ray12345 If it’s not too much trouble would you mind sharing a translated screenshot/snip of LHY’s ‘Tiger Fish’ Taobao OCK-2S product page showing the -116dBc ‘upgrade’ option. As I had a look at the OCK-2S product page but it has only limited deets - as below - if you’re not registered.

Many thanks

where can you get this version?
I ordered mine through AliExpress - very fast & efficient, money back if not happy. Excellent unit!

Is there in fact a different model or is it sample variation?
