IAR -- when you're serious about audio & video

IAR accepts no advertising, so we can tell it as it is.

IAR explores products and concepts in more depth than others do.

IAR teaches you how products work,

         and why they perform well or poorly.

IAR is based on professional science, not amateur gossip.

IAR correlates observations with scientific analysis,

         so you can believe IAR's reviews.

IAR conducts its own advanced research, to keep you

         ahead of the state of the art.

IAR's pioneering research, developing new testing & measuring techniques, and teaching the giant Consumer Electronics A/V industry how to perform our new tests, is presented in IAR's print issues, # 1-79 plus Journals 1-5.

Print issues:

IAR is more like an encyclopedia than a magazine. Print

         issues give you a basic education, with vital information

         that's constantly relied upon in our future reviews.

For the huge pile of all previous issues #1-79 (7 volumes) plus fat Journals 1-5, send $283 domestic, $368 overseas air. Individual volumes (specify volume numbers, 1-7) are $44 each domestic, $59 each overseas air.
