This is the predecessor model to the R530 with same amp specs.  It is a super clean 100 watts/channel at 0.007% THD.  That is about as clean an amp as I've ever seen.  As far as I can tell, everything works on this unit - AM, FM, FM Stereo, CD (Aux), Phono inputs.  The radio presets are working.  

This came with a remote.
