What is the cause of this film?
Many have said that an amp is an amp and all things equal will sound the same. Same with DACs.
I don't agree with this as I'm finding I can hear much more information with better gear. So what is the area of circuit interest to improve resolution output to the headphones?
And yes, I know it's the sum of all parts but some parts are more critical than others.
It depends on the how the builder tunes it.
hell just looking at freq response curve for amps. They output different curves. Some are ruler flat, some are not.
then you have impedance on the inputs and outputs
Remember, speakers are not flat resistive load (ie, 8 ohm flat from 20hz to 20khz). They vary.
I used to have a pair of magepan 1.6qr which show a load of 4 ohms from the manufacture.
the real issue is that below 60hz, the load drops to around 2.6 ohms. Depending on the amp, might make the speaker sound anemic in the lower end. well of course! 2.6 ohm load is a hard load to push for ANY amplifier. :)
