Great sound from your favorite cartridge(s)

This vacuum tube phono preamp provides versatile options and settings for a wide range of phono cartridges — from moving magnet, to high- or low-output moving coil — so you can dial in the perfect sound for your system.

Characteristic tube warmth for your vinyl

The characteristic warmth of vacuum tube output helps create an effortlessly inviting soundstage. Two pairs of gold-plated RCA inputs and two pairs of gold-plated RCA outputs let you keep both of your favorite rigs connected without having to change cables to switch between them.

Convenient adjustments

The Pro-Ject Tube Box DS2 features adjustable input capacitance settings for moving magnet and high-output moving coil cartridges, plus gain-adjustment options to fine tune for the best sound in any given configuration. A switchable subsonic filter protects your amplifier and speakers from power-wasting low-frequency rumble below 20 Hz.
