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.
Compatible with both MM and MC cartridges. It offers connection for two turntables plus two selectable line outputs and a continuous-
ly 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 compo-
nents including tube output and polypropylene capacitors are audiophile-grade and guarantee a breathtaking sound experience.
A perfect upgrade for ambitious vinyl lovers!
