Anyone here tried the Gustard c2 clock cable?
Or would the built in clock on R8 be the same as the DI-20 clock?Is there a way to check what firmware is currently installed on my R-8 MK2? I bought it second hand and want to be sure it has the latest firmware installed. Also, if I get the DI-20 Accusilicon 90/98M Edition. Would I have to change the firmware to the External clock version?
You have to upload the fw and verify the checksum. But in fact, there are only two fws available, one allowing the external clock, the other is the regular version (no ext clock). In the settings, you will see if the user interface allows it or not, so which versïon you have.

Thank you for the info. What is the User interface program chip and DSP? Are you talking about upgrading the opamps?You have to upload the fw and verify the checksum.

The di20 uses the same Accusillicon clocks (98/90l) unless you buy an old one used. Then it could be 48/44 1 clocks, same brand.
You are better off getting an external clock after changing the user interface program chip and dsp fw (if you don't have the ext. Clock option) than getting the di20, which will gives maybe just a small upgrade sonically speaking. If any. An ext. clock would give a significant upgrade, even a cheaper one. The ext clock has to have a 75ohm out.
Behind the faceplate, there is a chip on socket that needs to be changed. The dsp needs to be flashed through usb using a usb blaster, following the update procedure. Not easy to setup.

Any suggestions for a cheaper ext. clock?

Exept when you change the fw and mcu program to enable ext. clocking on a r8 mkii . The bnc in becomes a clock input and it's 75-ohm.I think you pointed out last time that the clock connections are all 50 ohm?

You have the option to get 75-ohm from factory.Wow! This feels awkwards. I hope Kingwa changes all the clocks to 75 ohm and simplifies this...

Ext. Clocks offer 50 and 75-ohm about equally. Some say 50-ohm is better.If you live in Europe, not really. Because if we order anything from outside the EU we'll pay at least 2X the retail price if not much more. In my case, this was not even available for the R8 Mk2 at the time I bought mine.
And of course my comment was regarding all the Audio-gd gear. I think it would be great if Audio-gd went with the pro-audio standard of 75 ohm clock connections, which has been around at least since the 1980s.
Why do mutec and many others, including Cybershaft offer it? There is a reason.Ext. clocks don't offer 50 and 75 ohm equally. The only 50 ohm clocks are in consumer/hifi, and they're probably less than 0.1% of all clocks. The 75 ohm clock has been a standard for over 40 years. It was a bad idea to go against the standard, and this caused another wave of connectivity issues. It's even worse than I2S incompatibility, it's senseless and for no benefit.
