Diy extension cable for Omega 2

[Tony]

I have a spare cable for the Omega 2, which had broken close to an end to the phone, and I would like to make an extension cable with it.

I also have a spare Pro bias female connector, which I had taken out of my SRM-727A when adding a normal bias out on it. I was wondering, how difficult would it be to use such connector on the spare cable, to make the extension cable I need? Should I use any particular care (with solder, for example) on it? Will it supposedly sound as good as the Stax 'official' one?

Thank you!
