The Phono Box RS2 has a steel chassis which is covered by screwed aluminium panels. The construction of the model brings high quality rigidity and excellent isolation against interferences. Working with hundreds of fractions of microvolts so this way everything is playing its role. Phono Box RS2 is available in silver or black.
The Phono Box RS2 is set out to be the ultimate phono preamp, in the highest class. With features like it being fully discrete, a fully balanced dual-mono device with split passive RIAA and DECCA equalisation results in no expense being spared. As it is designed to achieve the best possible sound with extensively adjustable, suiting it to any system, environment or personal listening taste.
Hidden circuits involve no operational amplifiers and the end result is a more natural, vivid and dynamic sound. They are complicated to put together and involve a greater variety of components but the result is a truly high-end sound. Elsewhere the Phono Box RS2 circuitry is fully balanced throughout. The + and - signal chains are treated individually for absolute signal integrity which means less unwanted noise and interference. It’s because of this layout that the phono stage measures so well in its signal-to-noise ratio.
After many hours of listening tests and many years of experience, the design team decided to employ discrete circuitry in similar attention to detail is employed throughout the cartridge matching options. The phono box rs2 has eight optional setting for gain,ranging from 40db to 70db. The quality of the electrical circuitry is crucial for a good listening experience so it needs to be incredibly silent - Hence for the electrical design choices made.
