As large as a small file cabinet and weighing 223 lbs, MBL's most powerful amplifier, the Reference 9011, is a tour de force of electronics design and implementation that will set you back $53,000 if you're a single-ended stereo enthusiast, or $120,000 if you like pure balanced mono.

Computer audio is more than just a pleasant distraction. For the jaded reviewer, USB digital converters and the like are an escape from that humdrum, if only because they bring with them so many variables: myriad combinations of different platforms, storage devices, operating systems, device drivers, media players, codecs, word lengths, sampling rates, connection protocols, and more. Challenging though they may be, computer-audio products are a tonic for reviewers inclined toward apathy.

The magic numbers, for Salon Son et Image, are 25, 100, and 10,000. Canada's first and largest high-end audio show, whose 25th-anniversary show arrives March 23–25 (press day March 22) in downtown Montreal's Hilton Bonaventure, expects to set a new attendance record as up to 10,000 visitors explore 100 exhibit rooms.

Over @Stereophile, we received a tweet from follower Henry Gessau:

Henry Gessau. Henry Gessau! Who is this mysterious chap? He must be some time-travelling, sound-saving avenger! Color photography was not widely available until the 1950s, so based on his profile picture, Henry must have lived sometime between the years 1850 and 1950 and then tweeted into the future! But forget the man. What about his message?
