Be not confused, the sofa itself is not listening or if it is, it is not telling. The Listening Sofa is generally found in the hinterland of The Listening Room, but it is not haphazardly placed as if The Cat in the Hat were in charge of the affair. Oh no, it is positioned a specific number of inches from The System into a magical zone which is purported to be the epicenter of The Listening Experience.
Is there anything to know about sitting on the sofa you may ask? Good golly, yes. Apparently if you are slightly off center, the chances of achieving total audio consciousness evaporate like spit on a griddle, so here is an important tip:
If you are ever invited to sit on a Listening Sofa, wait for your host to sit down first. If The Audiophile sits toward one end of the sofa, position yourself in exactly the same place on the other end for optimal aerodynamic balance. Use a ruler or a foot-long submarine sandwich as a measuring device if necessary. If, however, The Audiophile sits precisely in the middle of the sofa, assume you are supposed to sit on his lap. This will not improve The Audiophile's listening experience, but it will measure his sense of humor and/or his capacity for profanity.
And that, my friends, is audio winning.
