Hi, Corey, Do you have the details on "The Prague Compromise." Jay McKnight and I know it happened, but what changed? The public EQ specs didn't. It seemed like a bit of a wink wink nudge nudge type of thing. Jay and I have written about it two posts on my Blog. <<http://richardhess.com/notes/2006/05/17/cassette-equalization-the-4-db-ambiguity-at-16-khz/>> <<http://richardhess.com/notes/2010/10/08/cassette-equalization-redo/>> Thanks!
