Quoth wikipedia: The first Compact Disc for commercial release rolled off the assembly line on August 17, 1982, at a Philips factory in Langenhagen, near Hanover, Germany. The first title released was ABBA's The Visitors (1981).

I tried to find Tyll's state of headroom post, and I couldn't. Do the old threads from the sponsored forum just disappear after the manufacturer stops paying? There has been good discussion in some of these threads, and it seems a shame for it to be lost.

I often browse headfi by looking at the post lists of favorite posters. I've noticed that Tyll hasn't posted since December 21st. I figured that he was just taking a holiday vacation, but it's been over a month now. I miss his excitement and his amusing and informative posts. I hope all is well...
