Tube phono-preamplifier


Premium phono preamplifier with tube output and high-end sound!

This precision tube phono preamplifier benefits from outstanding circuit technology from Dr. Sykora and uses ultimate components. Compatible with both MM and MC cartridges. It offers a connection for two turntables plus two selectable line outputs and a continuously variable selection of input impedance for low output MC cartridges while playing a record! Other features include input capacitance for MM cartridges and switchable subsonic, that prevents your amplifier and speakers of ultra-low rumble below 20Hz. All components including tube output and polypropylene capacitors are audiophile-grade and guarantee a breathtaking sound experience. A perfect upgrade for ambitious vinyl lovers!
