For Gustard R26...which bang for the buck: DDC or LHY OCK clock?


I've been enjoying this dac for several months now. I have tried USB and COAX and now I2S.

There is a noticeable improvement in each of these inputs. I have read many of the discussions here regarding both DDC and external clocks. I am wondering which of these would give more bang for the buck. The Gustard goes very well with my tube amps.

I am considering the LHY OCK 1 or 2 for clocks and undecided for the DDC.

I used a company called pasternack.com in California.  They make a lot of different specialty cables.   

For the 50 Ohm cable I chose a cable with 50 Ohm BNC connections and a 50 Ohm cable rated to 4gHz bandwidth.   I did the same with the 75 Ohm cable.   I probably could spent half but I wanted the best quality for the $$$    if you want to go all out the have similar cables that are true mil spec.    Those were a lot more and I think my choice was probably  more than adequate. 

You can chose crimp, solder, in some cases low flux solder.  My 75 Ohm was $50 and change and the 50 Ohm was about $80

@oddiofyl Wow.  Looks like they can make just about anything. I'm guessing it's a much better deal than a branded audiophile cable. 

They look like good quality.  It's a digital pulse or wave they are sending to each device, not an audio signal so it should be fine if they are wide bandwidth and are the true impedance.  .  I bought a WireWorld BNC to RCA and it was $120 so it will be interesting to compare the Pasternack.com cables.   

I bought an equivalent of the Pasternack from Mini-circuits, another specialist manufacturer of RF cables and other stuff for industry and lab use. Selected it based on very good specs for shielding and low levels of internal reflections, the best specs I could find for BNC terminations when measured at 10Mhz.

It sounds good vs some other cheaper BNC cables I had but unfortunately not as good as an AliX LMR-400 clone which is in turn some way behind the Harmonic Tech Digital Copper III. It seems there’s more in play here sonically than just the fundamentals of shielding level, accurate impedance, good terminations and low reflections.

For those who use the OCK-2 for their R26 (or any of the other Gustard DACs) is there any preference for the square or the sine output?
