What Is Input & Output Impedance, And Why Should I Care?

It's a specification you see a lot when shopping for preamplifiers and amplifiers for a high end audio system: input and output impedance, expressed in the ohms. Watts are much more easy to understand relating to eventual experience, as well as frequency response bandwidth. But impedance?If you've ever wondered what sonic effect input and output impedance have and what role they play, settle down for this one because Darren explains it all. The discussion of impedance ultimately brings up capacitance in cables, so that's a cherry on top for the cable deniers. But it's all wrapped up in the same concepts, and this one is a can't miss episode for those who want to know more.Earlier in the show, listener questions are answered, covering topics like dynamic range compression and speaker wall construction philosophies.This week's album recommendation is a rare throwback, to a blues master of the 20th century. It's an album that was in Darren's first audiophile library, and which remains a favorite many years on.  This podcast is powered by CommonGround Cables Whisper power cable.
