The StudioPhonno is in like new condition, no issues. Includes original box and manual. Great sounding phono stage but I decided to upgrade after upgrading my turntable.

StudioPhono 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.
With selectable gain and loading, you will be able to tailor StudioPhono to match nearly any moving-magnet or moving-coil cartridge on the market. A readily accessible bank of toggle switches can be found on the unit’s underside to quickly make adjustments without the need for any tools.
Two selectable toggle buttons on the top of the unit can engage Mono or Subsonic filter mode. If you're a fan of mono recordings, vintage or reissues like the Beatles in Mono box set or the Mobile Fidelity Sound Lab Bob Dylan Series, the Mono mode will come as a revelation. It will improve image stability and generate richer tone.
