I recently bought 2. It is my first foray into the world of power cords as most of my equipment is older but I have used them to good effect on my CDP and pre-amp. They replace stock, so not much of an ultimate comparison. They work well (well made, etc.) and I figure they will make a better standard to judge others by if I get carried away in the ever upgradeable future. The buying experience was excellent from GTT Group.
