The following is a direct transcription of copy appearing on the outer carton in which Sansui's J33 loudspeakers came.
JET STREAM... A mighty current of air created by the earth's rotation, a vast, silent stream which flows between heaven and earth and from which there seems to come, moreover, consoling music to fill the hearts of men, awe-inspiring, supernatural, cosmic music which enthralls all who hear it.

JET STREAM... Which girdles the earth with its sash. The vision which seers have of man is not one which comes from the cosmic vastness.

Is this not also the case with Arthur Rimbaud, Johann Sebastian Bach, John Coltrane and others of their stature?

Through the words and notes of their poems and music there always comes an impression of clarity. This is the supreme song of liberation of many, of one whose heart is filled with the desire to soar up into the realms of infinity and whose look is serene.

It was the same with Robert Goddard, the illustrious rocket scientist of Clark University in Massachusetts. It was this man who, in the spring of 1899, climbed a cherry tree and, gazing at the plain which stretched away toward the East, exclaimed, "Oh if only we had the means to fly to Mars. What a wonderful thing that would be." Such was the mind of this man!

At this moment he had the vision of the ancients, who had likewise looked into the cosmic infinity, the same dreams as the Egyptians, the Babylonians and the Mayas long before. Prayer, this is cosmic language addressed to God through music. Glory to God in the Highest, and on earth peace, good will toward men. (Bach-Extract from the "Mass in D Minor") When, free from all cares, you are reclining beneath a shady tree drinking good wine, as the Greek philosopher recommended, you also can experience this vision of splendor. It is at this time that you will understand that the music which captivated you came from out there, from the Jet Stream.

Let us hasten! Let us proceed forthwith to the world of the Supreme Love!

Let us join the celestial JET STREAM where infinite and eternal hope flow in abundance!

Personally, I think they're smokin' a bit too much of that ol' celestial jet-stream, if ya know what I mean...
