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