Introduction The M-stage is a fairly basic headphone amp. It features 2 sets of RCA inputs on the rear, which are selectable via a switch on the front panel. It also has a line out which enables the unit to be used as a pre-amp. Aside from the input selection switch, the front panel features a single 1/4" headphone jack and a volume control knob. A power switch is located on the rear, just next to the IEC power cable receptacle. It really is a very simple design. The only somewhat unique feature is the pair of gain selectors on the bottom. Users can easily switch from 0, 10, 18, or 20 dB of gain, independent for each channel, with the simple flip of a few dip switches.
