Norma Audio has been developing its digital products for over 20 years and presently manufactures a comprehensive series of absolute top class digital sources.

Norma’s reference digital source is the DS-1, and it’s a masterpiece!  The DS-1 gives you absolute musicality at the highest level.  We have sold digital set-ups exceeding $25,000 and have direct experience with many other high priced digital products as well.  I can honestly say that when it comes to digital, Norma gives you the best sound I know of for thousands less than other brands which don’t come close sonically.

The Norma DS-1 source gives you a state-of-the-art CD player as well as a complete set of digital inputs.  If you think you know your CDs well, we encourage you to listen to them on a DS-1 and see how different they sound.  We guarantee you’ll be quite surprised!  The DS-1 has both a full bandwidth USB input (192.0 kHz) as well as 4 SPDIF inputs, coaxial, optical and XLR. Therefore, all the features for an advanced digital source are contained within a single frame, and they are able to meet even the most demanding user’s needs with no limitations.

Norma’s other products are the CDP-1 which is the CD player version of the DS-1, the DAC-1 which is the DAC only version of the DS-1 and the HS-DA1.  The HS-DA1 is available in two versions.  The standard version has all the features of an evolved DAC and is equipped with 5 full-bandwidth digital inputs (24-bit, 192kHz, USB and SPDIF), and both an RCA and XLR analog outputs.  The HS-DA1 Pre has a variable output with an outstanding preamp section.
