A marvel of technique and another exponent of the renowned South Korean perfectionismas well as another demonstration of HiFi ROSE’s know-how in its relentless search for absolute sound. Defined by its creators with the eloquent adjective “Absolute True Fidelity DAC”the RD160 is a stylish piece of electronics that stands out for its incredible level of engineering refinement that it incorporates, with the aim of bringing to its maximum expression the conversion of digital audio signals to the analog domain and the succulent addition of a price without competition in the most exclusive High End field. The first solution worth mentioning is the ROSE DPC module (“Digital Processing Core”), in which all processing blocks are designed to maintain a optimal precision and thus guarantee a extraordinarily natural sound. Specifically, it synchronizes incoming content with unprecedented accuracy using a OXCO watch (“Oven-Controlled Crystal Oscillator”) high precisionwhich formats them in I2S, being particularly useful with “Hi-Res”, when applying synchronization and locking processes to them with the aim of minimizing “jitter”.
Furthermore, the circuit in charge configuring and managing the user interface is completely isolated of the path traveled by the digital audio signal, completely eliminating distortions and interference in it. The second key technological element of the RD160 is the so-called ROSE CIM (“Completely Isolated & Moduled”) Architecturea topology designed to maximize sound quality via strict modular structure. Specifically, the HiFi ROSE DAC uses a scheme based on two “chips”the first of them being in charge, a AK4191of the filtering stages (it is possible to choose between 6 filters) and the initial delta-sigma conversion, while the second, a AK4499EXis responsible for the conversion to the analog domain. By separating the analog and digital blocks, perfect isolation against noise is achieved during the tasks carried out by each section, a signal to noise ratio extremely high and extraordinary musicality. Additionally, by assigning individual DACs per channel and using a fully balanced symmetrical architecture for the analog output stage, the RD160 exhibits outstanding dynamic range and reproduces with millimeter precision the subtleties of the different recordings, complemented by a stereo image clear and precise.
Another relevant feature of this exquisite electronics is the ROSE NRA (“Noise Reduction Analog”) Filterintegrated into the analog stage with the aim of achieving a flat frequency response that covers the lower octave of the spectrum, with the corresponding absence of drops in said response and, therefore, a restitution without limitations from the low end to the ambient details located in the high frequency range. Logically, running these impressive functionalities without limitations implies that the relevant power must be completely free of impurities. And, in fact, that’s how it is, thanks to three linear power supplies ultra-low noise custom madewhich supply power to the digital input stage and the left and right analog output stages, drastically reducing interference and crosstalk between them. As a result of this configuration, the RD160 takes the clarity and dynamicsoffering a deeply immersive listening experience. The HiFi ROSE is completed with a construction of the highest levela groundbreaking aesthetic in line with the brand’s reputation and a connectivity very generous (with two external sync inputs included) that will satisfy the needs of particularly demanding consumers and equipment.
