Should've added "subjectively"
Otherwise some that didn't read from beginning might thought this is the result of controlled objective test, which is the norm on this forum when doing comparison.
Long time reader first time poster here.
I'm really interested on this topic of output impedance. I have a V2 which I enjoy using it as DAC for my active speaker and also as headphone amp for my headphones. The output impedance never bothered me before as most of the time I'm using planar headphones. Since the recent discussion on how output impedance alter the sound I want to explore more on this rabbit hole.
I fortunately also have Tin T2 to test. I use it to compare between DX3 Pro and NX4DSD, which have very low output impedance. I don't have equipment to do volume matching so it was manually adjusted as best as my ear allow me to. After listening to numerous songs, especially on bass heavy genre, try as I might but still I could not hear any difference between the 2 devices. Dissatisfied, I try my dynamic driver headphone which is 35 ohm impedance, still can't hear any difference. Why is it so?
What controlled objective test have you done to say what you have said on this post?
