The vp130 is a tube phono preamp with a built in headphone amplifier for use with moving magnet and high output moving coil cartridges. The vp130 is designed to amplify an RIAA equalized phono signal to a hi level signal. Since the unit utilizes tube circuitry the resulting output signal is more warm and musical than solid state preamplifiers. The real kicker aside from the price and stellar sound is that its manufactured in the US. Design that delivers high availability, scalability, and for maximum flexibility and price/performance. Manufactured In United States.
