Hi @txenakis
Congrats on the N-05XD. I've been considering one for some time. Cybershaft OP21A would be a great choice, as claimed by some esoteric owners. Albeit with a long wait period after placing an order, and is expensive too. I also saw some esoteric owners claiming very good results with a Teac CG-10M. After dark also makes clocks for esoteric and Dcs. But iam not familiar with their range. You basically need a 50 ohm / 10 mhz clock ( dcs is 75 ohm / 10 mhz so won't work).
I also read that with external clocks, the three below points are important :
1. Keeping the clock always on for thermal stability and accuracy. The teac displays the oven temp on its vu meter, to show when the clock has reached optimum temperature.
2. Isolation from vibrations. So a damping stand or isolators might be a good addition. I've read that for micro vibrations at such low level, isolators with isolation balls of carbide or germanium work well. There are some from the usual companies.
3. Decent to good quality 50 ohm cabling.
On a different question, will you be streaming via ethernet or from a streamer. Anyways, it may be a good idea to get a clock with multiple outputs to sync your network switch, transport etc. Network optimisation is the current area of focus. And clocking plays a part. For that reason alone I would choose the teac over the cybershaft. All the best 😁
