Summary: I feel I must respond to the other,bizarre review of the RX77. I am using the unit now with 2 speakers and find it to be one of the best,unadorned stereo receivers around. The sound on any of my cds is full and detailed. I listen mostly to classical,opera, Broadway and jazz and have been very satisfied with the sound.There is a direct switch, but I prefer to leave it off so that I can regulate the bass. There is no Dolby, Pro Logic etc.
