[QUOTE="Shonver, post: 950104, member: 34"] From memory: (a) The Zobel exists to ensure that the amplifier has a load at high frequency, to ensure stability. (The loading of the amplifier affects the feedback loop and thus stability margins; loudspeakers typically have a rising impedance at the top end). (b) The purpose of the series inductance is to protect the amp from overly capacitive loads; this, too, can affect stability. Output inductors are typically in the 1uH to 20uH ball park (very small) and are benign wrt affecting its frequency response if done right. I have a serious problem with quirky* audio equipment that require special cables. It really should just be plug 'n play. [i]*I'm trying to be nice...[/i] :angel: [/QUOTE]
