i just got my CA-14s today, and noticed that their cable isn't that long i would like to use them in an open setup, but the cable is only about 5ft long i have a mini jack extender, will it effect the sound? should i invest in a high quality one? also does anybody use the omnis and cards at the same time? which one should i run through the pre amp?, and which one is which one has a red strip around the mini jack?
