Ps there will be no difference from resistance to impedance of wire even if paired . There will be a capacitance. Wires attached next to each other it will be minimal . Now twist them and now you may see a small difference . But consider the very small amount of amperage passing through the wires for headphones and it's a waste of time .

Feel free to ask me if I can help I will. Good luck

Well my current wire configuration has a total of 48ft. of 26AWG wire per channel. Assuming what you said is true, then why would there be variances from -so far- from 48-70 ohms? Could the manufacturing vary that much with planar magnetics?

Back to our regularly scheduled program - What does everyone's cotton look like inside the grill? Since I had mine modded by a 3rd party, what is the 'reference' of these two since left and right are different. I know there will be slight variations across all of us, but I am curious.

 

You will also see the 'hue' I am talking about in the third picture. I used the camera on my phone, but disabled flash, and am showing a reflection of the ceiling so you can see the varying shade of color.

 

 

No idea on the cotton. Wish I could confirm sumthin'. Currently the system is in 19 pieces, as I re-configure it for digital play tonight away from analogue. Glad you posted that pix, as it makes it easy to see now what y'all were talking about. Yup, I got Piano Black... happily so!

 

What I suspect - without proof, mind you - is that HiFiMAN is rolling with whatever it's getting from the supplier, from batch-to-batch.

19 pieces, dang! Reminds me of my 9.2 home theater system and why I haven't bothered to take it out of storage yet lol. I don't want to de-rail the thread, but would you mind PM'ing me what you got? If you don't want to, I don't blame you lol :tongue:

Please post me the question as I have read the thread for the last three pages and I do not understand what you are trying to do. And I am not goofing on what you are doing. I'm sure it will make sense to me when explained.

:wink_face: Can't be considered derailing if I'm using the HE-6 to hear my system. The breakdown only sounds like a lot because I'm short on space, so I'm simply swapping in different cables and components for either digital or analog playback. Normally, I just have everything hooked-up. I hope to be moving soon...

 

Basically, just swapping in the music server, DAC, USBridge, G-22000, a bunch of Wireworld cables ect...

Those wires are just threaded through the hole and soldered to the wires from the drivers? They look like just tied inside to prevent them from being pulled through the hole.

Brunk . Forget about the wire . It is made under very very critical parameters. So wire is not the variable . Now if you are measuring the headphones with stock wires I can measure mine now with my dvm and tell you what get and I can then measure just the wires and the deduct the wire from total and this would be the restinace of the planers alone. Will this help you ?

Ok hereisnwhat I have . Color is black but a little ire descent . Bought from woo audio, about a year ago.

Leads of dvm .3 ohms. Wire is much higher then I thought it would be. Stock copper with 1/4 tip is .8 ohms per wire . Minus the .3 in leads is .5 ohms per wire times 4 that is two ohms wow. The cans measured about 50 ohms each side after deducting the wires.per side. Now don't they give these phones a nominal imp of 45 ohms. This all seems ok. But if people are getting a variance of 50% . Well I cannot beleAve this is from manufacture . Maybe there is copies being sold here.

That's correct, and yes they are tied in a knot inside the cup for a clever strain relief

I am currently unable to measure my HE-6 with stock cable because it is hard wired. Yes please measure yours with the cabe and tell us what the results are. Instead of measuring the cable itself, for sake of greater resolution on a standard meter, measure it from the hifiman connector on the ear cup itself. If you're unable to do that, then just measure the cable and report the difference. Thanks! Keep in mind though that I have 48feet/14.63 meters of 26AWG cable per channel.

Thank you ALRAINBOW. Hopefully someone knowledgeable on planar magnetics can provide an explanation, assuming cables are not making this big of a difference.

 

Can anyone else measure their stock, and non-stock cables and report their findings?

 

I haven't heard of fakes being made, but we may now only be discovering them if that is the case. Though honestly I can't believe someone would go through all the trouble of gold, same weight, etc. and find its way into authorized dealer's stock.

So basically you made a 12 foot cable and is 48 feet cause it's a balance . 26 gauge is really small. That is what my iem cables are. I am not sure but the stock I have looks like 20 gauge and copper stranded. If I were making cables for mine I would double the wires this will get you down to about 18 gauge . Keep in mind unlike most headphones these really do use easily ten times more watts then most other headphones.

In answer to the idea of such a variety in impedance readings between pairs, I've seen it. They've been from 39-60 ohms though pairs are usually within .2 ohms of each other. The last pair I measured were 41.2 & 41.3 at the 4 pin.

Clever indeed. I have another pair of the same stock copper cables. I'll hard-wire them using double stock cable, biwire.

I haven't measured the stock cable since I don't have a caliper, I believe this was asked before and they are 24awg.

I have 4 conductors per channel (2 for + and 2 for -) for a total of 8 wires. The cable is 12ft. long. 12 x 8 = 96 ft total. For each channel that is 48 ft. For each +/- signal that is 24 ft.

 

Here's is the cable i have.
