Description

The Norma HS-DA1 range represents a new generation of DACs designed to play the content of high resolution music files at their best. They are designed with high functionality and flexibility in mind. Their technical capabilities match those of equipment costing many multiples more and beyond the specifications, all aspects that are relevant to the sound reproduction have been given the utmost attention.

Staying within an accessible budget, you can finally truly appreciate the actual quality of high resolution files without the limitations imposed by inadequate implementation. Conversion and sound quality, operational capabilities and versatility place the NORMA HS-DA1 range at the top of high-end DACs in this price range. The fully modular architecture turns this DAC into a unique product, which is able to meet even the most discerning user’s needs and can be easily updated in the future.

The Norma HS-DA1-VAR offers all the features of an evolved DAC and is equipped with 5 full-bandwidth digital inputs (24-bit, 192KHz, USB and SPDIF), and both RCA and XLR analog outputs. It is equipped with variable output levels, a remote control and the ability to conveniently select between a fixed and a variable output mode. In this way, it is possible to connect a power amplifier directly to the HS-DA1-VAR. The option to control the volume level offers the possibility to eliminate a pre-amplifier, thus achieving a more direct musical path and eliminating a set of cables.

There are many DACs available in the market today. Most of them are variations of the same mass-produced circuitry that may give you a good, reliable result. Alternatively, the Norma HS-DA1-VAR is a made to order, low volume, high quality design that has resulted from 20 years of development by the one designer and hand built by Enrico Rossi himself. Loved by a growing number of audiophiles around the world, the Norma HS-DA1-VAR will bring your digital music to life.
