I'm in process of discovery via new streamer. Using network xe card at present, next will be usb xe. Will be comparing vs motherboard ports as I go along. Have no doubt JCAT cards will be far superior, advantages of better power supplies and filtering on these cards.
I'm powering my custom build streamer via Optimo S ATX and JCAT nework card with Uptone JS2, Optimo is one amazing LPS!
