Premium phono preamplifier with tube output and highend sound!

This precision tube phono preamplifier benefits from outstanding circuit technology from Dr. Sykora and uses ultimate components. For the first time a

variable selection of input impedance for MC cartridges can be done 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 polypro-

pylene capacitors are audiophile-grade and guarantee a breathtaking sound experience. A perfect upgrade for ambitious vinyl lovers!
