You might not be familiar with the name Norma, but as soon as we heard it in our Demo room, we had to have it. We first came across the brand at the 2019 Hifi Show in Bristol and immediately wanted to have a longer listen. The CD players have incredible detail, with a natural musical soundstage. If you are in the market for a new CD player then Norma should be added to your audition list. We think you will be blown away by the performance.
Norma Revo DS-1:
NORMA is proud to present the new DS-1 Digital Source. It is a significantly interesting product, both for its considerable technical content and for its extreme versatility, naturally combined with the rigor of the NORMA musical tradition.
In addition to a CD reading section, that represents the evolution of the REVO CDP1R , the NORMA DS-1 offers a complete range of digital inputs. There is a full-band USB input (192.0 KHz) together with 4 SPDIF inputs; Coaxial, Optical and XLR. Combined in a single chassis are all the functions of an advanced digital source able to satisfy without limitation the needs of even the most demanding user.
In the REVO DS-1 the same conversion section and the same output stages are used that have made the REVO CDP1R famous and widely appreciated whilst able to distinguish itself at the top of world class production with its musical quality.
Whilst we witness the proliferation of converters for "liquid music", conceived only with attention to the parameters of the pseudo-modern technicalities and the reduction of costs, to the detriment of the potential sonic performance of high resolution, NORMA proposes a "Universal machine", extremely sophisticated in all the important aspects for sound quality. Finally it is possible to appreciate the real quality files in high resolution, not limited by the influence of an inadequate implementation. The completeness of the NORMA DS-1 offers the possibility to manage and store all the digital parameters, independently for each input. For example, it is possible to activate the over-sampling function at whatever frequency the user wishes which can also be deactivated if not desired. Select the Master Clock source between the low Jitter Local oscillator or the input signal oscillator. Finally, you can change the Up-sampler parameters, the digital filter response, the absolute phase and the volume of the output signal. All this is through local commands, or by remote control.
