No not yet.
But I have a PLAN…

It is but one ingredient of my full secret sauce recipe along with sprinkling my frozen tears over them (cryo treatment) and the thermal cycling treatment and the hi-freq cancellation treatment, along with the too secret to mention stickerator treatments.

And all of these combined will be applied during the re-build of this amp while optimizing the component placement and thus minimizing the length of my wire with gain for zero loss of ANY of my precious electrons.

And research has shown that the loss of our precious electrons is an under reported problem of epidemic proportions which has been plaguing the audio community for decades now.

But I have a PLAN…

Could anybody point to any link or source where I can see how a MINI XLR connector (for an audeze or meze headphones, for example) should be soldered properly. The regular 4 pin XLR big connector to the amp, that I have seen it solder a few times and there is plenty info on youtube, but those mini XLR that has 4 pins but only 2 cables, there must be like a right way to do it, so that it is a more resistant job, or something like that? any help would be welcomed, thanks.

The below is for Audeze and also works for ZMF (not sure about Meze). I don't know what (if any) importance there is to tying pins 1 and 4 together and pins 2 and 3 together. Pin 1 is the positive and pin 3 is the negative (or ground) for each earcup. I made a cable for my ZMF's using just pins 1 and 3 and leaving 2 and 4 bare-naked for each connector and it works just fine.

Other than making the 4 pim miini-xlrs universal (sort of) by tying pins 1&4 and 2&3 together for audeze and zmf or any other set of cans that use this arrangement, it would drop the Ω thru these connectors by ≈ 1/2 which isn't really a big deal due to the actual amount of current involved in the 1st place.

However I would NOT wire up the 3 pin xlrs by tying pins 1& 3 together for a truly balanced connection…
Pin 1 is chassis/shield ground and pin 3 is (-)signal which should NOT be tied to ground.

Hmmm. Not sure I understand. There are only 2 incoming wires into each cup's mini-XLR (for the ZMF anyway). Pins 2 and 4 are not connected to anything in the cable. If I solder a jumper between 1 and 4, and a jumper between 3 and 2, how does that reduce the resistance? Technical idiot question....

That is a really stupid connector for headphones.

In reality the audeze 2's and 3's that I have only use 2 pins (of the 4) so jumping the other pair of pins is pointless.
In fact that was what I was going to do (use all 4 pins) with my 2's & 3's but audeze glued the cables into the wood 'body' of the earcups.
That really isn't totally a bad thing, and actually from a reliability pov makes lots of sense…

However it also means I don't have access to the unused pins to be able to use them to reduce the pin to pin contact resistance by using all 4 of those pins in those connectors.
And many would argue that this amount of resistance coupled with the amount of current being sent would/should make no difference to the sound.
And using stock audeze cables I would agree, but then we all know the stock audeze cable is 'sub par' to begin with so no wonder opting to use all 4 pins (if it were even possible) is pointless.

But when using aftermarket cables this 'limitation' may be noticeable, however I can't verify one way or the other because those 2 extra (unused) pins are not readily modifiable.

Mores the pity…

So the latest word on my super tweako OPT's is they should be shipped early next week.

I'm still jazzed!!

I have a Norne audio cable incoming for the ZMF's. Be interested to see whether pins 2 and 4 are connected in it. And I have no idea if those pins are connected inside the ZMF earcups...guess I'll put a meter on them and see.

 

[johnjen]

I would hazard a guess that since they are 300Ω HP's that they only use 2 pins and not all 4…

Just say'n is all…

I have a tracking number fiwibida, fiwibida (that's supposed to be a tongue flapping at you…)
hahahahahahahahaha.

geez the smilies on this site suck, like in big time.
Have I mentioned this recently?

Not that I remember. but then I don't remember what I had for breakfast this morning.

 

[johnjen]

I can relate because there are 2 parts of the day, Lightime and Darktime and sometimes they seem to blur or blend together.
And it doesn't seem to matter because I do the same things in both of them, which can make for compounding confusion!
hahahahahahahahahahahahahahaha

Just a quick update.
I'm still waiting for my tweako OPT's to clear customs in NY where they arrived up on Aug 17th with nary a peep since.

To say I'm both disappointed and anxious is an odd combination of emotions.

[johnjen]

If only.
If only I had waited 1 more day.

Because my tweako OPT's from Bulgaria are due in tues or wed (today or tomorrow).

WooHoo…
