Just got the silver S15 that match with my Luxman, first impress me is the bass thats much better then ESS. Running android is very convenience for me to install youtube music and lot of local radio apps thats outputing 44-48k but you also can upscale all source to DSD. I have installed a 1T M2 SSD for storing my source files and that Sound is much better then my ifi zen stream before. The SSD also can used for android storage that saving youtube music locally. I also pluged TV hdmi to ARC port for my Netflex / Disney playing movies. So far so good. But one thing i want to complain is the remote is using BT..... as I'm using hey google to switch on/off all things by infraRED.... even the trigger cable is included but my amp dont have it ;( and also missing Wake on LAN.
