PS Direct Stream Vs. Lumin X 1 Sound quality difference?

Ozzy, you cannot plug a fiber cable directly to the X1, only a SFP Transceiver. Your answers are very vague. Please be more specific of what you are doing as I would love to give it a try if I'm doing something wrong.

Yes, I am confused as well reading the last two comments. Let's get the terms settled and confirmed so that everyone is clearly communicating and describing the connections. 

LUMIN - Fibre Networking (luminmusic.com)

The link above shows the X1 fibre connection. Looks like a SFP is used.

@ozzy I think the X1 does not have a built in transceiver, or at least mine doesn’t :) I have installed and tried different modules, it can be removed and replaced as it is shown on the diagram.
