RIP Amy. Back to Black Deluxe makes thanks to the song choice and the incomparably soulful voice really fun - as long as you listen to your iPod or howler cubes. There does not stand out particularly what you have to listen if you want to listen to the CD on a system once only a little louder. Amy's voice is then completely distorted in the upper layers. At first I thought even to a loss at the LS in the treble range, but another CD was able to dispel these fears and a brief search for "Amy's Back to Black" and "sound" confirmed my listening experience. Very bad (something inept in recording / mastering a fairly recent CD production), but perhaps there is soon the "Remastered Deluxe Edt"?
