Hi Mike. I have the Piano Classic, which I assume is somewhat similar to the Cera. From my experience, it takes at least 500 hours before they come into their own. They will sound good up until that time, but they kind of take on a new life after that. The other fun thing is any changes made are really noticalbe. I have changed all of my components, cables, placement, ect.. to get the most of the Tidal's. What I learned is, there does't really seem to be a "getting the most" out of them. Their potential will be as good as the room and upstream stuff allow.
