The Phonitor Mini is a very high power solid state headphone amplifier which features >130dB of dynamic range, courtesy its 120V operating voltage.

It also offers a mono setting. This amplifier has a single 1/4" output and RCA and XLR inputs. Maximum output power (@ 1kHz) is 2 watts into 300 ohms and 1 watt into 600 ohms.

I purchased this amp less than one year ago from Sweetwater Sound as a demo unit and am the original and only owner. I purchased this amp to drive a pair of Sennheiser HD-800's, which I am selling. My Chord Mojo drives my Beyerdynamic headphones really well, making the Phonitor Mini available for sale.
