Talk about a power forward!   This fully capable A/V receiver is definitely not the kind of “wimp-component” you might find at the beginning of a competitor’s lineup.  In contrast, the Marantz SR4002 brings you all the circuit sophistication and performance you expect from us.  The only thing missing is the cost of ownership.
