I have the LHY OCK 2. I have a mix or 50 and 75 ohm gear. I have a Mutec MC3+USB reclocker USB converter. That has a 10m input and is also a master clock generator. The Mutec is connected to my Lab 12 DAC 1 Ref via a DH Labs coax.
I also have the clock connected to a LHY SW 6 and my Teac VRDS 701t Transport.
My digital sources sound great. Crystal clear , I can listen a long time without fatigue
I ordered 50 and 75 ohm bnc cables from Pasternack. I was able to spec 50 ohm cable and connector and 75 ohm cable and conn.for each type. This is important because not all cables are terminated with respect to impedance.
