Those of us who in the UK bought a lifetime subscription to TiVo will naturally be wary of such things. My point is that there seem to be alternatives to Roon at much lower prices or even free and I am unclear what its edge is, never mind price. I have been told it is the additional information and selection criteria it can offer, yet a cursory glance at AssetUpnp suggests it offers similar features.

What am I missing? Does Roon somehow offer better sound quality for example?
