In the archive at kallhovde.com there is a PDF [1] a scanned Pioneer brochure from the year 1987. In this PDF, p. 10 extracts from the HiFi Vision 12/87, where the A-441 has been tested are. In the amplifier / mid-range category, the A-441 took 1st place in the test field "with consistently very good grades".
