What's a 1210? :) I don't know about that one.
Technics 1210s, the turntables - no decent club on earth would be without one until the 2000s when CDJs started taking off (and even today many still have them)

Oh sure, ok. I couldn't remember a headphone with that number.

12. dd mini angled...........................52.4...39.4...39.4...39.9
......dd mini angled 2.5-4.4...............52.5...44.9...51.8...68.3
the 2.5mm socket is like those used into sources' cases, so expect longer durability (time will tell).
but conductivity is very poor (the worst by far). the culprit is the flexible gold plated ribbon/pcb used to connect the contacts (thin and not great material probably). the resistance is the same as some 1.2m cables (+plugs), go figure.
Any chance of getting the newer adapters from ddHiFi reviewed?

Then there's also the mark II variants:

i won't buy them (i'm plenty of good quality adapters), so the only chance i measure them is the manufacturer or a distributor or a particular sends them to me

I see this part
"3. Calculate section of each signal. SignalSection = NumberOfCoresPerSignal * CoreSection. If your wire is 4 cores, each signal will use 1 core (2 for ground); if your wire is 8 cores, 2 cores are used per signal. Let's imagine this is your case. SignalSection = 2 * 0.1 = 0.2 mm2 (which is equivalent to 0.51mm diameter = 24AWG)."

What if the wire is 2 cores?

Good cable to tame upper mid bite and treble? 2-pin.

if the wire has only 2 cores, it's a mono (not stereo) wire. you need 3 signals minimum for stereo sound: left, right, and ground. if you get stereo sound when using that cable, then there are 3 "cores" inside (2 cores -left, right- plus jacket/mesh carrying ground), or 4 cores inside (two separated cores into each external "core"). in the case of using metallic jacket for ground, it's difficult to calculate the equivalent section for ground (you'd need to know the number of threads of the jacket, and the section of each thread).

to tame upper mids and treble, i'd better try rolling tips or equalizing. quite more effective. if you want some little help from the cable, you should go for copper cables (not silver plated copper nor silver). search in my list for copper cables where there are comments like "dark" or "bassy" (upper mids and treble are less present in comparison with lows and mids).

Thanks! When a seller says 2 core coaxial, I assume it is using the jacket for ground?
