Gustard N18 Pro LHY FMC switches.

@tkrtrb125 not sure where you are located but here in Boulder County, Colorado I can buy an N18 PRO on Amazon and have it in system for 30 days.  If I don’t like it I can return it for free (note that I am a Prime Member, which can be worth it just for the ability to try Hi Fi stuff basically for free) - I’ve thought about doing it, but I often think I might be better off with a DAC upgrade - I’m currently using a X26PRO with an AfterDark external clock

@boulder_bob I haven't heard the X26pro, but after a little Googling, I think you'd gain more by going to the X-30, or maybe the R-30, than you would from adding a N18 pro. I went from a R-26 to the X-30 and the difference was pretty significant. I believe you could get one on Amazon and try it. 

@sls883 thanks - good input!

A question for anyone who uses or is familiar with the Gustard N18 Pro.
My source is a PC with Play Femto installed, which I use to stream music using the Qobuz platform.
To access the PC's network card (a JCat XE), I follow this path:
Vodafone fiber router -> Ethernet cable -> Cisco Business switch -> Ethernet cable -> FMC -> Fiber optic cable -> FMC -> Ethernet cable -> JCat XE network card.
The output from the PC to the Conrad Johnson ET5 preamp follows this path:
JCat XE USB card -> USB cable -> AudioGD Di 24/HD interface connected via BNC cable to an external 75-ohm Afterdark Emperor Double Crown sine wave clock -> HDMI/I2S cable -> AudioGD Master 7 DAC.
The aforementioned external clock is then used as the clock for both the interface and the DAC.
The AudioGD DI24/HE interface, in addition to two 10 MHz BNC inputs—one at 50 ohms and one at 75 ohms—also has two identical outputs, acting as the master clock when using an external clock.
I'd like to use the Gustard N18 Pro in place of the latest FMC module and connect its BNC input to the interface's 75 ohm output so that everything is connected to the Afterdark external clock.
If I understand correctly, the N18 Pro's clock input is 50 ohms.
My question is:
Will I have jitter problems when connecting to a 75 ohm clock that has a sine wave?
