I pay a flat contract of 20GBP for 100GB per month, which satisfies all my music streaming needs. For reasons that I don't fully understand, it sounds better than FTTC (Fibre to the Cabinet) or FTTP (Fibre to the Premises).

With a 4G cellular router that takes a SIM directly.

I'm trying to think what you call it. Cellular data? 4G.

I use PowerPoint, which has easy tools to use.

It's a TP-Link MR6400 4G router/modem in one. Mobile data works better for me than the landline-based broadband (better sound quality).

Yes, my router is powered by a Paul Hynes PR3iEHD 12V LPSU and it definitely improves the sound, as does the MeiCord Opal from it to the ER.

I will leave this to @AfterDark. to do as it will be their sponsored area and I do not have one of their products.

Thank you, John. I was just listing all the things I could think of that bore consideration, apart from phase noise. I understand that drift is not of any importance to audio applications (although it might matter to a ham radio operator).

Do we know that for sure? What about other noise, such as ground plane noise? What about amplitude variations? What about waveform quality, especially in the case of squarewaves? What about isolation of multiple outputs? What about impedance accuracy? Frequency drift?

Agreed, all of my work in this direction (Black Ravioli footers, tungsten cube, DoDo Mat sound deadening, Schramm door stop on top) have helped with reducing vibrations to the sensitive clock.

I am feeding the LKS DAC with AES so yes, it's reclocking and USB/SPDIF converting. Yes, I'm aware that I'm potentially breaking the moat via the clock cables. However, it sounds best with both reclockers fed from the master clock.

The BG7TBL requires 12V at around 2A for safety (it's rated at 18W). So the answer is no.

As previously posted, I am using the BG7TBL DAPU OCXO clock for both the ER and Mutec MC-3+ USB. After many trials, I can confirm that it enhances the performance of both. It is a better clock than the internal Mutec one to my ears. I am using Canare LV-77S cables, very short 30cm ones, 75 ohm matched throughout. High quality linear PSU, soon to be further improved by swapping to a Coherent supercap PSU being built for me.

Try as short a clock cable as you can manage. What is the cable you are using? Also, make sure the BNC connectors are fully secured both ends.

For my part, I am hugely indebted to both Alex and John for all the information and encouragement they have given to those of us who have experimented with an external master clock. I started this thread really to discover whether a ridiculously inexpensive clock sold for radio hams would work for audio applications. It does, rather well - job done! I believe quite a few of us have these clocks now and are very happy with them. Thanks again.
