Duh.....I just noticed that the newly released Lavaudio DS600 1.2 looks different from the 1.1, so you should be able to see which you have without opening it up.
- The Version 1.1 says "Lavaudio" on the top, "DS600" is on the front left and "DSD" on the front right, plus their are 2 "Hi-Res" stickers on top/
- The Version 1.2 says "Lavaudio Just for Fever" on top, "DSD" is on the left and "DS600" on the right, plus 1 long sticker on the top right.
