Pro-Ject Tube Box DS2 Tube Phono Pre-amp

Pro-Ject Tube Box DS2 Tube Phono Pre-amp – Pro-Ject

“Totally Tubular” The Pro-Ject Tube Box DS2 world class phono pre-amp

Double the fun with 2 complete pre-set inputs
This versatile vacuum tube phono preamp provides highly flexible options and settings for a wide range of phono cartridges — from moving magnet, to high- or low-output moving coil — to ensure top-notch performance that’s tuned perfectly for your system.

Tube amp silkiness
Its vacuum tube output helps to create a spacious soundstage with no noise, so your precious vinyl sounds exactly the way it’s supposed to. It has two pairs of gold-plated RCA inputs and two pairs of gold-plated RCA outputs so you can keep both of your favorite rigs sounding excellent without having to change cables and switch settings all the time.

Complete Flexibility
The DS2 features adjustable input capacitance settings for moving magnet and high-output moving coil cartridges, plus gain-setting options to better match your cartridge to your system. A switchable subsonic filter protects your amplifier and speakers from power-wasting low-frequency rumble below 20 Hz.
