There are requests to record outputs of two different power amplifiers and prepare a listening test with such recorded files. I have decided to answer the challenge again and recorded files from 2 different class AB amplifiers, loaded with real speakers. One of the amplifiers has about 6 times more power than the other one. The files were recorded at output power up to 20W/4ohm. The level was matched by analog path (blue Alps pot) and the files were time aligned by SW.
The files are in 96/24 format and can be downloaded as a zip file from the link below. Please download and unzip the files before listening to them

Please let me know if you can hear the difference between the files and if yes, which one do you prefer. Of course and ABX test result would be greatly appreciated.
Please feel free to use DeltaWave software by Paul
@pkane to analyze the files. I will have no problems if you post the results here, for discussion purposes.

Have fun!
