Thanks dude I think if I use pretty flat non coloring headphone at a normal listening sound it sounds good but if you crank it too much the sound get really loud and all weird.Have a look at @solderdude site- he sometimes measures impedance response https://diyaudioheaven.wordpress.com/headphones/measurements/
If Amir has tested them I think he does too- sure other reviewers too.
668B look pretty stable.
An 56-Ohm headphone can be driven by a headphone jack with a 220-Ohm output impedance, but there will be poor damping control.
It will give the headphones a bloated (louder, less detailed) bass and other weird sounds.
I would suggest investing into a modern headphone amplifier.
