The Phono Box RS2 sets out to be the ultimate phono preamplifier, in the highest class. It is a fully discrete, fully balanced dual-mono device with split passive RIAA and DECCA equalisation, resulting in a “no expense spared” phono stage designed to achieve the best possible sound. It is also extensively adjustable, suiting it to any system, environment or personal listening taste.
After countless hours of listening tests and many years of experience, the Pro-Ject design team took the decision to employ discrete circuitry in the Phono Box RS2. Discrete circuits involve no operational amplifiers (op-amps), and the result is a more neutral, natural, dynamic, and vivid sound. They are more complicated to put together and involve a greater variety of components, but the result when utilised in a well-organised electrical layout is a true high-end sound.
