MoFi Electronics UltraPhono Phonostage & Headphone Amplifier

UltraPhono replicates the wide bandwidth transparency Mobile Fidelity Sound Lab mastering engineers demand. Tim De Paravicini, the designer responsible for the Mobile Fidelity Gain2™ Ultra Analog cutting system, assisted with the internal circuitry to ensure your analog system at home faithfully reproduces the music buried in the grooves of your LPs. UltraPhono also includes an audiophile-quality Class A headphone amplifier for intimate listening enjoyment.
