I was looking for an amp for connecting its HDMI inputs and control the sound of my HD digital decoder and its completion fit the bill perfectly. Moreover it is compatible 3D and allows to connect an MP3 player directly (and manage your iPod). I am not a music lover, so vis-à-vis the sound quality, I can say - and I suppose that in addition it depends on the connected speakers. But for my use: DVD, Blue-Ray, PS3 games, music and radio ... it is perfect for a reasonable price
