The Modi doesn't have a headphone amp or an optical input. I know my situation for my particular bedroom system isn't catholic, but I need three digital inputs, RCA, optical, and USB, as well as a volume control, with a price around a C note, that will decode most all hirez formats. If the volume controls the RCA outs this could be what I need. As that system is mostly TV with music mixed in ultimate sound quality although important, isn't the very top of the list. Really good will be just fine.
