Dynamic, transparent, and profoundly musical, the Rogue Sphinx v3 sets a new standard in affordable integrated amplifiers. Utilizing sophisticated circuitry borrowed from our most advanced designs, the Sphinx is able to outperform separates costing far more than this single box design. And with 100 watts of hybrid power, this integrated is capable of realistic volume levels that will rival the clarity and presence of the original performance.

The Sphinx v3 contains a discrete MOSFET headphone amplifier capable of driving even the most demanding headphones. An excellent user adjustable phono with 44/60dB of gain will accommodate your favorite MM or MC cartridge. Active and fixed outputs allow for the addition of a subwoofer or other outboard devices, and the active output is driven by the tubes for the best possible sound. A high capacity linear power supply provides tremendous energy storage to recreate the deepest bass passages while various regulated power supply stages provide ultra smooth sound in the midrange and treble. The machined aluminum faceplate is available in either black or silver to compliment the rest of your components and the optional remote further adds the convenience of remote volume operation.
