Can someone explain matching gears input and output impedence?For instance,my creek obh-11se has 100 ohm and 220 ohm output jacks. The 100ohm drives my 32ohm grados just fine.I always thought the headphone or speaker should have a higher impedence than the amp. Also,what kind of output impedence will drive a senn hd600, and why is a300ohm impedence so hard to drive if high impedences require less current drive?

This thread will help a little.
