Jack, Brian wrote weakest, not the only link. Of course, there are some superb speakers that are also inefficient that require substantial amps to drive them. But the general case is that the speaker is a critical transduction point where electrical energy is converted to acoustic energy. Converting energy from the mechanical deviations in the grooves of a record to electrical energy is another such transduction process, as is reading a disc with a laser. Passing an electrical signal through a system is less demanding than converting it to another medium. I think that may have been the point of Brian's observation. Thus, one might expect the biggest bang for the buck by attending first to the transduction process.
