The audio chain design started choosing a new Vacuum Tube Preamplifier section based on the Rossini CD Player REV2.0 output stage that gave us surprising results. Then all the parts have been matched to the preamplifier stage. Important changes have been implemented in every part, but especially in the power stage and DAC section. The audio quality resulting is astonishing! The Enigma Rev2.0 has a new more essential design with a line input on the front to be connected to a line output of a MP3 Player such as the iPod to meet the increasing interest in that kind of audio sources even in the High-End field. Also a Monout output has been added to connect a active subwoofer and a completely very efficient new software has been implemented.
