My wife often enjoyed making fun of how many optical disc players I had in my AV setup. When it was the most out of control, I had an HD-DVD player, a PS3 for Blu-ray movies, an Oppo Universal DVD player, and a Sony SACD changer for music. While DVD-A and SACD didn't catch on with lots of the public, some of us built up a collection of the titles that we want to be able to listen to, and we would like to avoid having an AV rack full of extra players like I do. Denon's new DVD-A1UDCI Universal Blu-ray player handles every format out there, including Blu-ray, SACD, and DVD-A, outputting the signals digitally through its HDMI port.
