All of the audio cables I have purchased from Monoprice are definitely premium quality. As an audio engineer I require top shelf cables and interfaces, often paying top dollar for them too! Somehow, mono price meets or surpasses top brands and sells them at a much lower cost. Thank you Monoprice!
This is a really high quality cable and I would give it a 5/5, however it doesn't mention just how thick the connector is on the 3.5mm side. If you plug this into for example the Line-in on your PC sound card, it makes it difficult to plug in speakers or headphones into the adjacent jack. It puts a lot of stress on the jacks
When I took sound out of my TV's minijack and fed it to my stereo, I got bad hum. I replaced the long RCA cable with a better-shielded one (a "Premium" one from Monoprice), and that cut the hum quite a bit, but there was still too much hum for me. So I replaced the splitter that goes from the minijack to the RCA cable with this "Premium," better-shielded splitter. The hum was reduced again, quite a bit, not to zero, but to a low, acceptable level. This was a good solution to my problem and worked the way I wanted it to.
