Free shipping: On all orders over 500 SEK
Experience true analog magic with the Pro-Ject Tube Box DS3 B, a high-class dual mono phono preamplifier featuring tube technology and a fully balanced design. This premium product from Austrian Pro-Ject Audio Systems is developed in collaboration with Dr. Sykora and is built with the finest components to deliver a warm, detailed, and dynamic sound that elevates your vinyl experience to new heights.
- Fully balanced signal path – With both inputs and outputs in balanced format (mini XLR or standard XLR), noise and interference are effectively eliminated, providing a cleaner and more musical reproduction – perfect for modern home environments with a lot of electromagnetic interference.
- Dual mono construction – Separate circuits for left and right channels provide outstanding channel separation, deeper soundstage, and natural dynamics.
- Continuous impedance adjustment – A unique feature that allows you to continuously adjust the input impedance (10–1000 Ω) directly during playback via a potentiometer on the front panel – no other manufacturer offers this to the same extent.
- Support for two turntables simultaneously – Connect two different cartridges (MM or MC) and save the settings for each input separately.
- High-quality tubes – Two E88CC/6922 tubes provide low noise, minimal microphonic interference, rich bass, and silky treble tones.
