Pro-Ject Tube Box S2 Phono Preamp

The Pro-Ject Tube Box Series 2 is a MM/MC Tube Phonostage with Discrete Circuitry & High-End Tube Sonics Tube Box S2 uses fully discrete circuitry – no operational amplifiers here (aka Op-Amps, used in simpler, more affordable designs but with some sacrifice to sound quality). The standard, user-replaceable tubes sound stellar out of the box, though the design opens the gates for sound-shaping via tube rolling should you want to take it a step further. Tube Box S2’s sonic presentation is full & relaxed with a blossoming midrange more typical of much more expensive designs. The stage welcomes most MM & MC cartridges on the market with a wide range of gain, loading & capacitance settings. The S2 series’ 2-layer aluminum/steel enclosure shields the circuitry from vibration and electromagnetic interference for more music, less noise. Suitable for MM and MC cartridges Precise RIAA equalization in two parts, passive/active Fully discreet circuit design without OpAmps 2x ECC83 tubes (replaceable) Front-sided Subsonic filter button Front-sided Gain control Ultra low noise circuitry with FET input stage Dual mono circuitry for optimized channel separation Polystyrene capacitors used where possible Gold-plated RCA in- and outputs External power adaptor and multiple internal power supplies Well-filtrated high-voltage anode power supply Sandwich aluminum/metal casing protects from vibrations and electromagnetic interference Available in silver or black Handmade in Europe
