Not all the Dick's Picks are HDCD. Later in the series they started releasing HDCD recordings. Keep in mind these were live soundbard shows for the most part taken from reel to reel mixes and not the best example of what hdcd can do. As a Deadhead I can say they sound way better than the non-HDCD Dick's Picks releases as well as the 150+ live shows I have in my archives.
