Using an external word clock with Esoteric cd/sacd players

Considering the use of an external word clock with my Esoteric cd/sacd player, it has a word clock BNC input. Wanted to ask two questions;
1.) Are you relegated to using only an Esoteric word clock device? or
2.) Can you use another manufacturer like some of the pro audio word clocks, eg. Antelope OCXHD, Black Lion, Tascam, etc.?
Thanks for your input.

But I’ve kicked around the idea of playing with a reclocker at some point, just to answer for myself if I can hear a difference. 

@toddrhodes

To my ears, there was a significant shift in capabilities of DAC's from before 2010 to after. I don't know what it was, but here's what I have heard:
Prior to 2010, HiRez was significantly better than Red Book playback.

After 2010, a number of DAC's made this difference almost, if not completely, imperceptible.  Whiel HiRez playback has been consistent, Red Book has really improved.

I wish I knew why, but I suspect better, cheaper oscillator chips hitting the market, or perhaps better receivers?

Anyway, point is, I have tried reclockers. You have to be aware they are not bit-perfect. But, they do work with:
  • Poor sources like cheap streamers (Google, Apple)
  • Old DACs

With new DAC's I can't hear a difference at all.

So, the answer is, this depends.

Generally, you want an internal clock on the Esoteric because, being closest to the spinning disc, and DAC, an internal clock has the shortest trace route, and will have the best chance at having a great signal.

The main reason to use an external clock is when using an external DAC. Some external DAC’s even provide their own clock out.

Second main reason to use an external clock is if a device has a poor one to start with. Clocks and their circuitry over the past 10 years are VERY VERY good though.


Best,
