I purchase this unit to replace my aging klipsch 2.1 system which actually have better bass , but be become balky and malfunction often . the Onkyo be simple to set up and run . it have a nice on screen menu that super over programing without have to interrupt anything . the sound be very good and crisp . it have amazing surround dimensionality for a 2.1 system . I like the fact that there be a minimum number of wire and that the remote easily switch between source . the one drawback be that the system must have the tv power on to function properly , there be time when I just want to listen to music from a internet source , but it do not work unless the tv be on .
