You said Oyaide HPC35 was "too bright", meaning the highs stood out more than the mids - shouldnt that mean the FR around the higher end of the spectrum be higher than the other cables? The DIY using LyxPro starquad OFC "bass slightly improved" - 120hz and lower should be marginally different with that cable?
Sure you might not have CSD graphs to check for ringing/distortion but the headphone/enclosure and amp is the same.
I just have a really hard time believing there could be any difference by simply swapping cables, especially when theyre all decent.
I guess my words were too exaggerated. Please take note, that my impressions for the 3 cables I mentioned, were for cables, not amplifier, not headphones. Meaning, different degree of differences. For example, when we say this headphone is warm, and that amplifier is warm sounding as well, the perceived degree of warmness is different, although for simplicity we just say both headphone and amplifier are warm sounding. On headphone the range of differences in sound signature is wider than amplifier. Likewise between amplifier and cable, the range of differences in cable is much smaller than amplifier. It is more difficult to perceive sonic differences between cables, than between amplifiers. So please read my impressions with the understanding that I'm talking about differences between cables.
Probably I would need a highly accurate binaural mics dummy head to measure the sonic differences of cables on the same headphone. I don't have those accurate instruments, so I cannot measure them. Measuring the cable alone using line out to line in on my sound card won't do justice.
Anyway, I used to be a 'cable skeptic', until I gain more experience with cables. The same with my friend, a sound engineer, till he experienced it himself. Yes, the range of differences is very small with cables, when compared to the range of differences we can hear when swapping amplifiers. So please read it within that narrow range of differences.
This thread is about MSR7 headphone, and we better don't start 'classic' arguments about cables here. I know some people don't care much with cable rollings, that's fine. My impressions are for those who care.
FYI, even if the Oyaide HPC35 is not my favorite cable for MSR7, it is my favorite cable for Fidelio X1.
