Pro-Ject Phono Box DS+


Premium class phono preamplifier with big display



This ultra low noise precision phono preamplifier benefits from outstanding circuit technology from Dr. Sykora, well-known from Phono Box S, but uses ultimate components. For the first time all setup options can be made from the front panel display, what makes circumstantial handling of mini dipswitches or jumpers obsolete. Exceptional performance and outstanding flexibility with almost any MM or MC cartridge make Phono Box DS+ the best choice in its price class. All switching is done by relais including a subsonic filter, that prevents your amplifier and speakers of ultra low rumble below 20Hz. Carefully selected amplifier modules and audiophile-grade polypropylene capacitors guarantee a breathtaking sound experience. Therefore Phono Box DS+ is a perfect upgrade for hifi systems of ambitious vinyl aficionados!
