    Why do amplifiers with a high output impedance have trouble delivering power/current to low impedance speakers/headphones?

    Hi everyone, I've read about damping factor, and how it relates to the control of drivers, and the corresponding changes that it can make to a frequency response based on the impedance curves of the amp and drivers. However, I've always noticed that amplifiers which have a high output...

    Hi guys, I haven't been able to find any information on this, but it got me thinking. Can corrosion, scratches or any other types of superficial damage to terminals or connectors negatively affect the signal quality? or are cables a matter of, if they have continuity end to end it should be...
