Hey the RTD1619DR upgrade seems not to be called UHD2000 Pro but UHD3000 instead. It basically seems to be an upgrade with the new RTD1619DR SOC and and also the new ES9068 DAC for the HiFi panel. Included are 32 Gbyte flash and also 4 Gbyte RAM like UHD2000 most likely. I hope they also improve the airflow/heat/noise when using it with a HDD for music playback? http://forum.zidoo.tv/index.php?thr...ng-the-uhd2000-compared-to-z9s-usb-dac.78722/ There are to be found a few other minor suggestions for improvements too. More details to come soon from Zidoo.
