This is your basic RCA cable. Probably of better quality than the ones you could buy at a supermarket. You know, the ones that start to have problems almos instantly if you are a heavy user and connect and disconnect your cables. These are better than those. Nothing to really write home about, but will do the job. Connect your cd-player to your amplifier, they will work well. If you are a hi-fi maniac you'll probably be looking at some more expensive cables covered with diamond coated silver or something, but if you want cheap basic cables these will do.
i bought one like these before and i came back to buy it again. it really does the job. i used one to connect my tv to my speakers n one to connect my focusrite to my behringer ms40. i would recommend it !
