Higher impedance headphones are more tolerant of amplifier limitations, but produce less volume for a given output level. Historically, many headphones had relatively high impedance, often over 500 ohms so they could operate well with high-impedance tube amplifiers. In contrast, modern transistor amplifiers can have very low output impedance ...
For example, a 32 Ω headphone driven by a headphone amp with a <1 Ω output impedance would have a damping factor of >32, whereas the same headphone driven with an iPod touch 3G (7 Ω output impedance) [5] would have a damping factor of just 4.6. If the 120 ohms recommendation is applied, the damping factor would be an unacceptably low 0.26 ...
600 watt transformers are widely available for contractors needing high power loudspeakers in constant-voltage installations. [12] Special-purpose transformers capable of handling 1250 watts down as low as 50 Hz are available. [4] One problem with high power, high current transformers is that fewer can be used on a single constant-voltage line.

The impedance of a line input is typically around 10 kΩ. When driven by a line output's usual low impedance of 100 to 600 ohms, this forms a "bridging" connection in which most of the voltage generated by the source (the output) is dropped across the load (the input), and minimal current flows due to the load's relatively high impedance.
