Pro-Ject Tube Box DS2 Phono Preamplifier

An Easy, Effective Way to Put Tubes Into Your Analog Chain: Pro-Ject Tube Box DS2 MM/MC Phono Preamplifier Features Dual-Mono Circuitry, Subsonic Filter, and Optional Wood Panels

Put the unmistakable sound of tubes into your analog chain with the Pro-Ject Tube Box DS2 MM/MC phono preamplifier. In addition to smooth, rich, warm, and detailed sound and accurate RIAA equalization, it offers connection for two turntables, two selectable line outputs, and a continuously variable selection of input impedance for low-output MC cartridges while playing an LP. Input capacitance for MM cartridges and a switchable subsonic filter that defeats performance-degrading rumble also come standard.

Built to last and deliver audiophile-grade satisfaction, Tube Box DS2 touts low-noise dual-mono circuitry, gold-plated RCA inputs and outputs, and solid aluminum/metal sandwich housing. Translation: Excellent channel separation, wide-scale dynamics, and vibration-damping quiet operation. And did we mention the optional wood side panels (see all the color and finish options using our drop-down menu above) look great, too?
