I rip my audio files in AIFF format for the highest resolution and recently purchased a car with a 3.5 mm iPod connector. This cable pulls the audio out of my iPod in the cleanest way possible, avoiding the iPod's volume controller, and sounds fantastic. I have A-B'ed it against the CD from which the files are ripped in the car's CD changer and the iPod sounds better. All this, and the cable is not fully broken in. I am ecstatic with this, as I feel no need to upgrade my car's Harmon Kardon sound system in any way anymore. Thanks Earcandy. Also, CablePro was a great pleasure to deal with as always.
