They do not only operate with heavy two-channel amplifiers. McIntosh is also big on home theater, perhaps especially the home country. But the processors and multi-channel amplifiers are quite expensive, massive and complex.

Not the new home cinema processor McIntosh MX100 and the seven-channel amplifier MI347.

The processor at the top of the image above has four HDMI inputs and one 1 HDMI output, all with support for HDCP 2.2.

They also have up to 18 Gbps bandwidth that supports High Dynamic Range (HDR), Dolby Vision, HD R10 and HLG where applicable. There is also support for 4K with up to 4: 4: 4 colors, Rec. 2020 colors and there is a 3D review here.

There are also digital inputs here, two coaxial and two optical, and you get 11.2 or 7.2.4 channels out of the MX100. Which has 13 balanced outputs at the back.

The MX100 has seven 32-bit digital converters (DACs) and support for MultEQ XT32 calibration of the sound in the room.



The seven channel power amplifier MI347, uses class D modules in the output stage, and delivers 2 x 250 w to the main channels, and 125 w in the rest of them.

The two cabinets are made to fit in a rack and do not need much cooling to function satisfactorily. The amplifiers can be controlled with RS232 and can be configured with entered data on a USB memory stick for easier installation.

Don't buy the European version

The Sony NW-WM1ZM2 is a fantastic piece of craftsmanship. But avoid the version for the European market.

The best buy in its class

The little brown NAD amplifier caused a sensation. No one had heard such great sound from a small amplifier that cost so little.

Prefers good recordings

Although the Elipson P1 is the company's first preamplifier, it is pleasantly free of bugs. If you're looking for an amplifier set at the upper end of the premium class, the answer may well be French.

Grows with the tasks

Elipson's power amplifier works treacherously small. But it's really a heavyweight that gets the best out of your best recordings.
