Reports

• Stereo magazine: Comparative test 07/1983;
• Stereoplay 12/1983: "Spitzenklasse IV", at that time the best integrated amplifier at Stereoplay was "Spitzenklasse I".

Stiftung Warentest (similar date): Highlighted the high performance of the A-500, but due to the overload protection by means of a fine-wire fuse, the overall rating was only "satisfactory".
