McIntosh MX150 7.1 A/V Surround Sound Processor (SSP)


On The Bench

For the audio tests, I used the balanced XLR outputs of the Oppo BDP-95 and I measured the XLR output of the MX150. The audio bench results were simply excellent. At 1 kHz, THD+N was 0.00057%.

Here are the results for 19 kHz, 20 kHz combined test frequencies. There is no visible B-A peak at 1 kHz.

The IMD measurement was 0.0003%.

While the MX150 does not have a video processor, it does have an onscreen overlay which means that there is a chance the video can be affected. I ran through our core benchmark tests for Overscan, Whiter than White, Blacker than Black, Luma and Chroma Burst, and Luma and Chroma Plate on the MX150. I did not see any problems with the MX150 in terms of these tests.
