The starting point of the tube phono preamplifiers from Pro-Ject is exceptionally affordable electronics, which, in line with the Austrian company's philosophy, includes genuinely audiophile solutions.
Thus, its circuitry is executed with discrete components and therefore omits the use of operational amplifiers, a solution that results not only in ultra-quiet phono amplification and highly accurate RIAA equalisation, but also guarantees a long service life for the entire product.
In addition, interchangeable vacuum tubes make it possible to modify the sound to suit your taste, with the lush mids and overall warmth of a much higher-priced product standing out at all times.
The Tube Box E is compatible with MM and MC capsules and is equipped with numerous gain settings that can be changed on the front panel, while the bottom of the unit has settings for a wide range of impedances and load capacitances, thus facilitating a perfect match to the capsule used.
Let us finally point out a 100% metal construction which effectively protects the Pro-Ject against electromagnetic interference and vibrations likely to adversely affect the sound quality.
