The VK-50SE uses next generation Unistage® topology to provide a new level of transparency and musical insight. A number of changes to power supply management, parts selection, and circuit layout contribute to a higher level of performance throughout the audio spectrum. This advanced Unistage® circuit eliminates the phase shift, signal coloration, and distor tions of multi-stage designs, while suffering from none of the lackluster dynamics or component matching problems common with passive designs. The VK-50SE has ultra-strong output capability and can drive even the most demanding power amplifiers.
