OK, I must confess that I never thought that in my entire life I would post in a DIY forum. DIY just don't go with me.
Well I am here finally driven by the exorbitant cost of balanced cables for the Hifiman HE-500.
Background is this. I have a HE-500 and I am planning to buy one of the Balanced DAC/AMP from Audi GD. They have 4 pin balanced XLR headphone out jacks. All the balanced cable solutions from third parties run into at least 150-200+ dollars plus shipping. Then I came across the cheapest solution from the Audio GD website. So I thought I will modify my stock HE-500 cable to 4 pin balanced XLR using this (just $30):
I believe I can follow the instructions and with the help of friend, I can sum up the courage to modify the stock cables. The advantage of above solution is that the stock cable can be used both as a balanced cable or Single ended cable depending on the need.
The only part I cannot figure out is to how to determine the L+, L- and R+, R-. The web site offers help as follows:
If you are unable to determine the nature of every wire in your headphone cable, you can use a ohms meter to test and verify, the L+ is short to "L", the R+ is short to "R", and the two GND is short to "GND" of the picture below.
I have absolutely no knowledge of the tools mentioned like a Ohms meter. My friend has a solder gun and a multimeter. Will that suffice? Also how can I check the L+ and R+ using the Ohms meter or a multimeter (if it can be used). This is the part where I need the help.
Please be detailed as how I need to do it. Should I plug the 6.35mm TRS plug in to Ohms meter while testing? I tried to search using Google, but I could not find out.
Thanks in advance for any pointers.
