Boasting a compact and stylish aesthetic, this state-of-the-art electronics benefits from the sophisticated architecture of HiFi ROSE's flagship digital source, the celebrated RS151, while offering a versatility and ease of use that allows it to form part of a very wide spectrum of audio configurations.
Equipped with two ES9027PRO premium 8-channel, 32-bit arithmetic ES9027PRO D/A converters from US-based ESS Technology, each with its own dedicated power supply, it uses one for the pre-out and one for the headphone output, thus providing a refined and agile sound suited to different listening environments.
In particular, the preamplified output section includes precision DAC circuitry for integration into the most demanding music reproduction systems, while its headphone counterpart, based on the HP Amp Architecture, is combined with four high-performance amplifiers to achieve optimum impedance matching, extremely low noise and high dynamic capability.
In the field of digital signal transmission, the ROSE DPC module, imported from the RD160 streaming transport, shines with unprecedented femtosecond precision and perfect alignment of the I2S wave trains.
As with the RS151, the RS451's analogue stage incorporates HiFi ROSE's innovative NRA (Noise Reduction Analog) filter, which eliminates noise and guarantees a flat response curve even in the lower octave of the spectrum.
It should be noted that this new streamer is driven by an 8-core, latest-generation RK3588 processor, which, compared to its predecessor, increases information processing performance by a factor of four and graphics processing performance by a factor of eight.
