Esoteric or CEC cd-transport

Purchased a CEC TL3N earlier this year, nice unit.
Has anyone heard any CEC DACs?

One question regarding my purchase. I see some non-factory upgrades on the back panel... What is it?

Alex...sorry I don't know. I knew there were several companies that were modifying these, but that isn't one I've seen.

I even searched for that image, but didn't come up with anything.

Maybe ask the person you bought it from, what was done.

I haven't seen that mod before either, but it appears to be an external clock input via BNC connector along with a switch to allow the selection of either the internal or external connected clock.

If you don't have an external clock connected I would assume that the switch should be set to "int" for the internal clock to be used.
