I personally heard the differences in cables and wiring on headphones. The differences are subtle but definitely there for sure.
I was skeptical myself but then, using a splitter and swapping immediately between headphones I heard differences like alo cryo copper sounding more heavy than alo cryo spc.
Once you hear a little, even negligible difference, than you will by nature want whats better to you even if it only makes a slight difference
Fair enough. No problem respecting your post. Very reasonably explained and I believe you.
I only have problems with posts that make cables sound,like a night and day difference... Cables that magically enlarge soundstage or add lots of air or treble, or change the FR all together... That's just silly IMO.
One must have convinced himself then as that's not even reasonable to expect. Cable does not make or break a headphone... Slight alterations only.
