I've had Pete's power cord for a while and love it! very transparent. I've also had his Speaker cable for a bout a month. They had 100 hours on Pete's cooker, but still needed to be run in as they where a little dark. They did open up a lot, but still need to open more in the mids. These are very good cables. As stated, a little darkness in the mids that need to open up as well but I'm very much trusting that it will open a bit more. This is one cable that as you continue to run them in , will reap great rewards. Pete what a great speaker cable!
