I have some of the magazines, and have always enjoyed looking at the photographs, graphs and schematics. I wish Japanese was not so hard to translate, the few times I have attempted machine translation I got largely gibberish in return.

Fun stuff to look at, and leaves you wondering why they are able to support such a magazine in Japan and no longer in the West, the cultural/educational divide in many ways is larger than we perhaps appreciate. Audio hobby magazines of this quality have not existed here in the U.S. since the about the late 1960s. (Audio Amateur and its successors, along with VTV and Sound Practices were maybe the last vestiges, but were tiny in comparison.)
