Amps do amplify yes... That is about the only correct thing you have said so far
lol this guy. The headphone jackets on power amplifiers and receivers are very often directly connected to the loudspeaker outputs. To prevent damage to the headphones and to the amplifier, resistors are placed in between. These resistors generally have values between 200 and 600 Ohm but drop to 50 too.
Here's the thing if a headphone has flat impedance, then we should see no difference in frequency response with different amplifier output impedances. The source of this is basically what is called a voltage divider, where the voltage drop from the amp output to ground is split between the amplifer impedance and the headphone or speaker impedance. Assuming the amp exhibits flat impedance with frequency, if the headphone has different impedances at different frequencies the voltage will be split differenty at different frequencies. That will lead to a frequency response difference from what was encoded in the input signal. But, if there is no variation in headphone impedance at different frequencies, then the voltage split is constant and the amp output impedance has no effect on frequency response
it's ok though they feed you guys a lot of grass. i only suggested keeping the output low because i was trying to avoid conflict from people that would argue with me but i suppose i should have just took the time to write this in the first place.
btw could you please tell me what you mean by this? "a) very cheap / bad" lol gosh i feel all warm and fuzzy inside right now
i generally try to meander around and act like i have a question and about this or that and then act like i stumbled across the answer and share with the readers. I do this because it seams to help people cope with what i went through when i first started but then also avoid the herders that get on here just to keep the thieving cycle of "audiophile" going.
This stuff isn't nearly as hard as people make it out to be.
