The amplifier outputs 100 watts per channel at 8 ohms and 160 watts per channel at 4 ohms. The new wattmeters with a double scale, graduated for a load of 8 and 4 ohms, are responsible for the display.
The first hybrid integrated amplifier in the McIntosh catalog was the MA252. It is largely based on the classic MC275 tube, but it does not lose the advantages of transistor sound. The preamp part is based on two pairs of lamps — 12AX7a and 12AT7, the lamps themselves are covered with protective covers. The output stage is transistor, and outputs an amplifier of 100 watts per channel at 8 ohms or 160 watts per channel at 4 ohms.
The case of the MAC7200 receiver is made in the unchanged McIntosh style with blue indicators, a black glass front panel with aluminum end plates, control knobs and a backlit logo.
The McIntosh MA7200 amplifier has 14 inputs: 5 unbalanced, 1 balanced, one background input for MM and MC cartridges, a pair of coaxial and optical, USB and a proprietary MCT. The digital inputs are located in the removable DA1 module: after some time, the user will be able to replace it with a more modern version.
The MA8950 comes standard with the DA2 digital audio module, it offers 7 digital inputs: 2 coaxial, 2 optical, 1 USB, 1 MCT, and 1 HDMI Audio Return Channel (ARC) only connection1. The DA2 is equipped with an 8-channel 32-bit digital-to-analog converter (DAC), which improves both the dynamic range and the total amount of harmonic distortion compared to the DAC in the DA1
