This is the ZEN STREAM streamer from iFi audio. - Overall, it's in beautiful condition (though it is used, so please forgive any minor imperfections from normal use. Please check the photos carefully before considering a purchase). - Fully functional (I used it with ROON, but all other functions worked perfectly). - Complete accessories (original box, power adapter, LAN cable, mode switching tool, antenna). - From a smoke-free, pet-free environment, used only in a dedicated room. I've repurchased this model before because the network connection didn't work well, but this unit works without any problems. I'm not considering lowering the price. If there are no purchases, I will gradually lower the price, so please stay tuned. Please consider this opportunity.
