I have c5i and think it's the cats meow. 60 watts gets you pretty far but not the nth degree if you like it loud and clear with less efficient speakers in larger rooms. c7i has more power and tuner in addition to dac and phono. Hard to fault other than that. Sound is liquid and dynamic with a big well defined soundstage. Bass is extended and articulate and well balanced finally top to bottom but not warm at all if that is what one seeks. These are true digital amps i.e. Analog inputs are converted to digital along with the rest.
