PROJECT TUBE BOX DS
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 polypropylene capacitors are audiophile-grade and guarantee a breathtaking sound experience. A perfect upgrade for ambitious vinyl lovers!
