I used a sine wave generator to test the difference between a modded side with an unmodded side, and most of the difference was at below 200Hz.
Thought I'd post a word of caution for people thinking of making, or having made, a custom cable for your AKGs:
Tell the maker to switch pins 2 & 3 on the mini XLR
(this assumes a standard config on the TRS end)
In more detail
general XLR convention is:
pin 1: ground
pin 2: pos
pin 3: neg
and usually on 1/4 or mini TRS, tip = pos = left, and ring = neg = right
so, pin 2 = left, pin 3 = right
BUT, AKG reverses pins 2 & 3, so
Pin 1 : Ground
Pin 2 : Ring/Right
Pin 3 : Tip/Left
In doing research into making a cable for my HiFiMAN HE-500s I thought I might try one for my Q701s. I came across a few posts that point out the fact that AKG does not wire in the standard way, at least for the US and perhaps elsewhere (I have no idea if there's a global standard for such things). That made me suspicious of the cable I had Redco make. Sure enough, left and right are reversed. Easy to test with a balance adjustment *sigh*
Now I'm definitely making a cable using some of the Mogami W2799 I got from Redco for the HE-500s project. I used a thicker version of the Mogami Neglex Quad when I ordered my custom cable from them, and that was a mistake. The W2799 is much better suited for headphone cables, being thinner. FWIW, I've been using a $200 cable from plusSounds on my HE-500s, and I can't hear any obvious, immediate difference between it and my homemade cable. Nothing against plusSounds. They were easily the least expensive of all the makers I checked out, and had the most options to configure a cable. If you're not a DIYer, I recommend them. And I'd recommend Redco for reasonably priced cables using standard wiring and connectors, either for parts or making the cable.
On the positive side, I'm going to recycle my old custom Q701 cable and make a pair of short interconnects for my Bifrost-to-Lyr stack. Silver linings and all that
Just thought I'd throw that out there.
I read about how the pins might have been reversed before, so when I made my own cable for the q701, I just used a multimeter instead to test; I was quite surprised to see that the pins on my set wasn't reversed, so the above might not be applicable to all q701s. FWIW, I bought mine fairly recently about 3 months ago.
Same thing when I tested the stock cables that came with it. Pin 2 was wired to the Tip, and Pin 3 was to the Ring.
That's a good point. Definitely worth testing with the stock cable to see how ones particular set is wired. Does that beg a question, I wonder:
What if AKG wires their stock TRS connector backwards, too.
Hmmm, not sure my brain is up to it at this vino-soaked hour
Thanks for pointing that out.
If both are wired backwards, then it becomes correctly matched , making it just a regular trs to mini-xlr cable.
the 2799 is a good choice. I made several cables for my headphones using stripped wires from it, and I couldn't be happier with the weight and ergonomics of the resulting cable (though I use it for a 6-8 strand braid).
See, I told you it's too late for this schiit
I was thinking about a stripped and braided cable to reduce the weight and make it more flexible. Research for another day, but if you have any tips or links, hit me.
Sure thing, I'll pm over a few useful links when I get off work in a few hours.
For the life of me I can't do the bass mod. The screws I'm using to twist just end up scratching plastic and moving nothing.
