I don't know how to scientifically analyze them to determine exactly what sound quality they offer or not. However, I do know that they appear to be very durable, at least in a way that will last a long time. And subjectively they sound good to me. So I bought 3 cables from this company and they all look, sound and feel great! I have these 2.0 RCA to 2.0 RCA cables in 1 foot, 3 foot, and 3 foot versions. 3.5mm to 2.0 RCA to connect to phone as audio source. I've owned it for several months now. All 3 have the same build quality and all 3 cables have no issues, no hum/hiss/hum. They sound very clean to me, and when you move cables to different sources, the DAC shows a varied sound and picture between sources. So I know I'm getting at least some really good quality with these cables. I would buy them again and recommend them if these cables were in your price range.
