Extreme hardglass CD

Hi, have you seen the advertisement for an extreme hardglass CD? You can be the owner of it for just $1,000. No kidding! I wonder why spending that much money into a "flawed" carrier (the "perfect sound forever" red book silver disc we all know) for perhaps 5% overall improvement in sound, while you can get a 30% improvement by doing the recording or remastering job in the right way (which is certainly not the case in many CD releases)? But I assume there will be people who will buy the disc (there are many rich audiophiles around you know). At least they will hear the famous Herbert von Karajan DGG recording of the Beethoven Ninth Symphony in glorious sound!
Btw, has any of you heard an extreme hardglass CD? If you have, please give us your impressions of the sound.
