Just got mine today, so here’s a little review incase anyone is interested. Can’t fine much info on this device. The Utility app barely works, but I was able to change my EQ to tower speaker. Line in seems to work with no issues. Streaming from the Definitive apps on my 5ghz wifi network works well too. I did have connection issues with 2.4 ghz, but could just be my router. Can stream from Pandora, but looks like you need premium for Spotify... No Bluetooth or YouTube streaming, but could always connect a Bluetooth receiver to get this.
Sound quality wise, I think it’s very good and seems more neutral compared to my Marantz SR8015. Some say the bass is weak, but seems good. Maybe because I changed the EQ to tower. Probably use the W Amp for every day music and SR8015 for movies. Not sure if it will play as loud as the SR8015, but I’m sure it can hit 90db+
