McIntosh MA9000: powerful and very expensive integrated amplifier

Company McIntosh has introduced its largest and most powerful integrated stereo amplifier MA9000. High power 300 watt per channel required a new design radiators, cooling vysokotochnye transistors of the output stage, and Power Guard modifies the signal peaks in the case of the possibility of audible clipping. A microprocessor unit for monitoring different parameters of the amplifier, including output current level, which should not exceed the specified limit. The McIntosh Autoformer technology maintains full output power when load impedance of 8 Ohms, and 2 Ohms.

The overall level of harmonic distortion does not exceed 0,005%, and the uneven -0.5 dB frequency range is approximately 20-20, 000 Hz, with -3 dB it extends from 10 to 100,000 Hz. The ratio signal/noise of the power amplifier reaches 114 dB, damping factor greater than 40. Part of McIntosh MA9000 included DAC and headphone amplifier, digital input represented by optical and coaxial S/PDIF as well as USB, in which case the DAC can take the signal 32 bits/384 kHz and DSD64, DSD128, DSD256, DXD352.8 kHz and DXD384 kHz.

Model McIntosh MA9000 different characteristic for the company, blue illuminated power meter and remarkable price of $10500. Visitors will be able to buy a new product later this month.
