Massdrop + THX AAA 789 Linear Headphone Amplifier, and upgraded iPower Low-Noise DC Power Adapter. This headphone amp made waves when it was released, as it was one of the best if not the best low-noise amplifiers on the market for the price. The amp uses fully separated channel circuitry, giving it very low crosstalk; and the included iPower DC adapter helps keep the noise even lower, to the point that the unbalanced output has the clarity and noise floor of a fully balanced amp. The amp also has balanced XLR output with higher power output with the same excellent low-noise performance as with the unbalanced 3.5mm and 1/4 headphone outputs. For inputs, the 789 has two pairs of RCA stereo inputs and stereo XLR for balanced input. Finally, there is a three stage gain switch that increases noise but also increases power output. Here is a full breakdown on the amps features, statistics, and power: https://www.audiosciencereview.com/forum/index.php?threads/review-and-measurements-of-massdrop-thx-aaa-789-amp.5001/ This is one of the original revision A models with a serial number of 03616 from March 2018, retaining the original Massdrop branding. It has not been run very hot, and has been kept on low gain and never went past half volume. Please note this listing does not include the original RCA cables included from the manufacturer. Includes an XLR to dual 3.5mm balanced cable, and 3.5mm to dual 3.5mm cable. These cables can be used for headphones with two 3.5mm connects in each cup, such as from HIFIMAN or other brands. As they are no longer needed, they are included with the amp. Please see pictures as they are part of the description & are of the actual item(s) you will receive.
