I already know what devices are under test, so I can not help that.
But I can hide the devices from my mate. I could put a blanked over the audio setup and just let him have the switcher.
Yeah I know. Thank you for the tips.
For me, this post is about making amp comparisons more fairly and it’s for audiophiles, who may not have all those specialized equipments at hand.
At first, I wasn’t aware, that precise volume matching can be done so easily, as long as the output impedance of the amps do not audibly affect the frequency response of the headphone.
You just need a multimeter and an online tone generator.
I will update this post with an easy tutorial on volume matching for everyone, because volume matching is a must for having fairer comparisons.
