I think apple headphone wiring is much too stiff
Are you speaking from having taken apart a set of earbuds and actually examined the wire? If so, I'm surprised you might think that because I believed it to be extremely supple and very fine, just as much so as the original silver Litz wire that my tonearm came with from the factory. Maybe Apple used different sorts of wiring over the years? I don't know, but the stuff I found in the set I had was perfect for the job. Again, it took a bit to get the ends tinned properly but that was just because I'm not an experienced technician in this regard. It did, however, challenge me to become better at it so that was an unexpected side-benefit of the exercise/adventure.
The wire is Van den Hul MCS 150M Cable.
I have heard this is excellent wire.
Slightly off-topic here but do you have a thread about that somewhere? Mine could really use it, the wires are beginning to fray at the tags and one is too short, from a previous owner's repair.
Sorry it has taken a while to address this, b4b, but no I have not done a thread on it.
This is a tedious job and it requires getting to know that arm really well and how it goes together. If you have that knowledge, or choose to develop it, you can take it apart to the extent needed and remove the old wiring, pull through the new stuff, and do the necessary removing/soldering of the old and new wiring. It gets pretty interesting once you get into the arm base, pull out the rubber plug and realize you now have to carefully disassemble/dissect the old wiring from where it meets the heavier wiring with the RCA plugs at the far end. I used some dental picks as well as an exacto knife to do this job and worked very slowly.....in the end, had a pretty good understanding of the nature of it.
Otherwise, there's Larry at Hollywood Sound who is the resident expert (and Nottingham rep here in the USA) who does a great job and will rewire your arm, inspect it and restore to factory specs for around $150 last time I checked. Before I did my rewire of the Spacearm, I just ordered a new Ace Space 10" arm from him, put it on the table and then proceeded with the rewire of the old arm thinking it would be a nice second arm if I wanted one. Well, after getting the new arm with the silver Litz and listening to that, then rewiring the old arm, I put the old arm back on with the Apple earbuds wiring and that is how I conclude there is no difference in the sound between the silver Litz wiring and this earbud stuff......
I am confident there are those (whom I both envy and have great sympathy for) who will be able to tell the difference, far surpassing my hearing ability. I hope I have shed some light on the matter.
