Everything about McIntosh’s MA9000 integrated amplifier is super-sized, from its 46kg weight and 300 Watts per channel power output to its baby hippo-sized frame.
This kind of thing is common in valve-based designs, but unusual in transistor circuits. McIntosh does it to ensure a more efficient transfer of power between the amplifier and speakers. This puts less stress on the electronics and makes the amplifier more load tolerant.
Look around on the back panel and you’ll notice dedicated speaker outputs for 2, 4 and 8 ohms speakers - that 300W per channel power figure stays consistent regardless. While matching the output terminals to the nominal impedance of your speakers is a good place to start, it’s still worth experimenting. In our experience, the difference in sound between the outputs can be significant, and the correct option comes across as obviously more balanced.
While checking out the nicely made multi-way speaker terminals, it’s hard to miss the MA9000’s impressive connectivity. It feels like McIntosh has tried to include every input a potential user is likely to need.
There are no less than eight line-level inputs, two of which are balanced, alongside digital connections in the form of a USB, two opticals and a pair of coaxes. The USB is compatible with files up to 32-bit/384kHz as well as DSD256 streams, while the others are limited to 24-bit/192kHz PCM.
