Sweet versatile piece from McIntosh, and a great addition to any system.
Can be used as a preamp since it has a volume control, as long as you don't have any other analog sources.
Also has an excellent headphone amplifier to drive your cans that was definitely not an afterthought add-on.
• The original McIntosh remote is included but it has developed some heavy "stickiness" from age.
• This DAC uses a muting circuit for the headphones that can sometimes cause audible "chirps" between tracks with certain streamers or amplifiers.

We start with a visual inspection of all internal components to make sure that there are no signs of heat stress or damage. Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect resistors and other passive components for signs of overheating.
After the visual inspection we connect the DAC’s RCA outputs to our Sencore PA81 Power Analyzer which simulates a real world input impedance and allows us to monitor the output on an oscilloscope. We are equipped to test optical, coaxial, and USB inputs at Redbook CD Quality. We start with a test signal to verify signal lock and proper output on both channels. If the DAC has balanced outputs these are also tested at this time. If the DAC has multiple Optical and Coaxial inputs they are all checked for proper lock. USB inputs are tested with a Macbook Pro.
After proper function is verified, we set the DAC up for a listening test to evaluate general audio reproduction quality and monitor for clicks, pops, or any other audible signs of issues related to dropped signal lock or failing audio output stages. We often connect DACs under evaluation to our long term test rig for a long test stint to verify stability under real world operating conditions.
