Unrivalled Performance and Unique Flexibility
Pro-Ject's Tube Box S2 phono preamplifier with a tube output stage offers unrivalled performance and unique flexibility at an incredibly affordable price. It's one of the most economical ways to enjoy the lush sound of vacuum tube phono gear that we know of, and the ultra-compact size means that the Tube Box S can fit almost anywhere.
The sonic quality of Tube Box S2 is extremely impressive, offering a big improvement over Pro-Ject's great sounding Phono Box S. It makes a big improvement over the built-in phono stage on many amps and receivers and offers a perfect upgrade for most analog hi-fi systems.
"Full Bodied, Natural and Warm"
"The Pro-Ject Tube Box is a clear winner with the Koetsu Black" phono cartridge, reports Phil Gold in his review of the original Tube Box S for EnjoyTheMusic.com. "The sound is full bodied, natural and warm, with a surprising degree of detail… The sound is spacious and there is good width and depth to the image."
Fully Discreet Circuit Design Without Op-Amps
Tube Box S2 is Pro-Ject's very first product to feature a fully discreet circuit design without using any operational amplifiers (OpAmps). It also is the first product to come with replaceable tubes for tube rolling and sound-shaping. This gives you many options to pick from and alter the sound signature to your preference.
A Wide Range of Setting Parameters
Tube Box S2 provides a full and relaxed laid back sound with lush mids, just like you would expect it from a much bigger high end tube phono preamplifier. It offers support for both MM and MC cartridges and comes with many gain settings to be switched on the front panel. Five variable input impedance settings are available to adjust to any MM cartridge. The 47k ohms input impedance setting is fixed and suited for high output MC cartridges.
The aluminum/metal casing is adapted to Pro-Ject's DS2 line in looks and protects against vibrations and electromagnetic interferences for superior sound. This is all-in-all a true high end solution in a small package.
