Hotbird that puck reminds me of my Sony ES that I had but was just mostly weight with felt on the bottom side, I'm more impressed with Oracle's set-up.
The Oracle addresses these issues in other ways. One area being when you actually install your disc onto the platform the fit is very precise, when you go to take the actual disc back off a suction has been created holding the disc in place and then releases, this is without the actual puck in place. Now the puck it's self is special, it has a Urethane compound ring that acts as a vibration damping trap and adheres to the disc. You have to peel the disc off from the clamp when you change the disc. I have put many disc's on and there has been no loss of adhesion but if it occures Oracle recommends you clean it with methyated spirits.
Once you put your disc on and then the magnetic clamp you must then install the aluminum top cover which is a very precise fit. When you remove and replace this you can actually see the the whole unit move up and down. The suspension is very precise and they give you a calibration tool to assist in accurate measurement and calibration of each suspension tower located on all four corners. With every piece of music you actually push the disc reset button to initialize the selected disc.
At the beginning I found it a little strange but now I'm use to it.
The remote is all Aluminum, front and back ensuring quality and is very serious in weight and finish.
The unit even has a separate power supply that is connected via 15 pin DC input which to me is good design wise and well thought out.
Pictures don't do justice for this piece, it's art and a statement on it's own. Every person who has come over since I got it are very impressed, can't wait to hear it and then I pass them the remote and they comment saying they have never seen anything like this before, right down to the remote is screaming quality.
