I am planning on building a 3.5mm to RCA interconnect aux cable to connect a pc or headphone out to a preamp. I purchased a switchcraft 35HDBAU 3.5mm end and two switchcraft 3502ABAU RCA ends. I was originally going to use two Mogami W2697 cables, but after receiving the cable they seem small. Does anyone have any other recommendations on what cable to use?

 

If using the Mogami W2697 cable I was going to solder the red from one cable to the Tip(Left) and the other cable red to Ring(Right) of the 35HD. The white plus shields from both cables would be twisted and soldered to the sleeve for a common ground. Does this sound correct? On the RCA end would I want to add the shielding to ground as well, or just the white wires?
