An exquisite, ultra-compact vacuum tube-based headphone amplifier that carries the best McIntosh tradition to intimate music listening.
Two double 12AT7 triodes are responsible for amplifying the incoming signal, while two 12BH7A provide the power necessary to attack all types of headphones with minimal distortion, all complemented by McIntosh 's iconic Unity Coupled Circuit technology, used in the first amplifier on the market. by the brand (in 1949!) and still present in such emblematic creations as the timeless MC275 power amplifier.
For the MHA200, the Unity Coupled Circuit transformers have been tailored to deliver the full available amplification power at four headphone impedance ranges: 32-100 ohms, 100-250 ohms, 250-600 ohms, and 600-1,000. ohms.
Another fundamental engineering element of this extraordinary headphone amplifier is that the aforementioned output transformers (custom designed and built to perfectly match the tube amplification section of the MHA200) are complemented by a highly efficient toroidal type power supply. and extremely quiet.
The MHA200 comes complete with three headphone connectivity options: two 3-pin XLR connectors for balanced left/right output, one 4-pin balanced stereo connector, and one 6.3 mm stereo connector.
