Phono Box DS


This ultra low noise phono preamplifier benefits from the same outstanding circuit technology as the Phono Box DS+ in a slimmed version with almost the same sound quality. This unit comes without display and relay switching, but at a more favourable price. For the first time, nearly all setup options can be made via front panel, making circumstantial handling of mini dip-switches or jumpers obsolete. Exceptional performance and flexibility with almost any MM or MC cartridge makes the Phono Box DS the best choice in its price class. A subsonic filter is positioned on the rear panel to secure your amplifier and speakers from ultra low rumble below 20Hz. Carefully selected amplifier modules and audiophile-grade capacitors guarantee a breathtaking sound experience. The Phono Box DS is a perfect, cost-effective upgrade for most high-quality hi-fi systems.
