MacMX-136.jpgMcIntosh Laboratories' MX136 is the company's top of the line audio / video processor that sells for a cool $10,000. McIntosh Laboratories has been an icon in both American manufacturing and the audio world for five decades. Audiophiles have long viewed McIntosh products as being highly desirable and in many circles even collectable. The McIntosh Laboratories brand has become so well known and respected that there is now a coffee table book on the company. Their unique look consists of a black glass panel with silver trim and backlight blue meters. The MX136, while lacking meters, keeps the tradition alive with silver trimmed knobs on a black glass faceplate, the main display window uses blue characters and the status lights are green, a very retro and classy look.

The MX-136 is geared toward consumers who aren't as concerned about the latest codecs found on Blu-ray discs but rather maximizing the performance of the traditional formats and the extensive collections already in existence (although the future codecs can be accommodates as described below.). This decision is made clear by the MX-136's HDMI ports which accept video only. In addition to the HDMI video ports there are 12 analog audio inputs and 11 audio / video inputs, an option internal radio tuner. The audio connections include two pairs of balanced audio connections and a 7.1 analog input. In addition to the slew of audio /video connections, the MX-136 features several control and trigger connections including RS-232 which allows it to be easily integrated into a control system. Features include the ability to custom name inputs, a second zone, night mode, video scaling and transcoding to HDMI and more.

The setup menu can only be accessed by the front panel and all settings are manually set. This is a bit of an abnormality in today's world of automated setup routines and room correction. The MX-136 is focused on obtaining the best possible sound within its chosen arena and this quickly becomes apparent. Many surround processors fail miserably when faced with the task of stereo music reproduction, not so with the McIntosh. The MX-136 can't keep up with McIntosh's dedicated stereo preamplifiers but does much better than most processors and probably a good number of stereo preamplifiers as well. As mentioned above, the MX-136 does not accept audio via HDMI, it must come in via traditional analog and digital inputs. In order to take advantage of the new advanced audio codecs one must use a source with multi-channel analog audio outputs and connect them to the MX-136's 7.1 inputs. Video transcoding was very clean and scaling was generally good with just a bit of softness and a few artifacts.
