An interesting thing of note for the Sony: if you did leave it in "source type autoselect mode" (or whatever it was called), the noise floor would be noticeably higher than if you configured each input for the type of physical connection to use. So at least on the Sony, not the panacea that it could have been. The hiarchy was set on the Sony, neat that on the Yamaha you could prioritize what connection to look for 1st...
