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

Ozzy, people say the noise is eliminated through the fiber but that may not be totally true. Using fiber requires putting two more conversion circuits in the path, the two transceivers.

Ozzy, How do you figure??? Unless the switch has one built in where you can plug the fiber direct into the switch (which the switch would still have the conversion circuit), you must use a transceiver on the lumin end. If I'm wrong I'm all ears and would love to try what you are talking about.

Ozzy, Lumins own website shows two transceivers??
