The new REVO DAC-2 represents one world’s best expression in the realization of Digital-to-Analog converters. Using the newly developed in house A-DAC.

With extremely low noise floors and a penchant for a more analog sound, the REVO line is sure to readjust expectations of digital playback quality.  Norma's desire for a more analog sound can be found in the heart of these units with the A-DAC proprietary conversion technology.  Why A-DAC?  Because A represents their pursuit of Analog. With proprietary I-V Conversion and a fully discrete analog section, the A-DAC is an advancement years in the making.

In a historical moment when we witness the proliferation of DACs for “computer music”, exclusively designed around the parameters of the so-called technical modernity and cost reduction to the detriment of the potential sound performance of high resolution devices, NORMA proposes a “universal machine” which is highly sophisticated in all the aspects relevant to sound output. You can finally truly appreciate the actual quality of high resolution files, without the limitations imposed by inadequate implementation.
NORMA is pleased to present the new REVO DAC-1 Digital Source. It is an extremely interesting product, both for its outstanding technical content and for its noticeable versatility, obviously combined with the rigor of NORMA musical tradition.
All of this at a very interesting price, considering the technical features.
