1. The delivery was super fast (Wednesday ordered, Friday delivered). 2. The inner conductor is made of steel-copper. Very stable. OK. 3. Whether it is a high-quality A + cable, I can not judge. After cutting lengthwise a fall against the "powdery" wire, so it is not really about a comprehensive braid. I hope that does not lead to increased interference. 4. Since I have no corr. Meter, I can not say whether it is actually a 120 dB shielding.
Summary: For the price you will probably not get a better quality. Price / performance ratio very good. After installation of the cable and other cables acquired opinion I had to improve my rating.
