Since I only a mini SoundStation (CD player to speakers) have standing in the hallway, I had the face of a tonally restricted mobile speaker system (Terratec Subsession Traveller 5) "pimp" the music source. A good Sony CD Walkman will be connected through this good jack cable to the speaker via jack. Compared to a lot simpler (also gold) jack cable makes the sound a big, positive difference. The music sounds less harsh, but soft and full and so much better. The purchase was worth it and I'm very satisfied with the quality of this high-jack cable.
