It is suggested to be used as a impedance matching buffer for electric bass amps (which usually have too low impedance inputs), as a cable driver for large stages, in complex effects set-ups, or as a recording preamp. The best way to correct for this is to insert a buffer stage between the 4S and the LM1875. The greatest comprimise in a Receiver is the use of a single power supply for all three sections (preamp,power amp, and tuner) The needs of the power amp section affect the preamp section,which degrades the sound.
