@Piru: You can sampling and playback 44.1KHz sound on a plain a500. Even 56KHz. We did it with my friend something about '93-'94 with Aegis Audiomaster IV if i remember correctly. Of course it was 8bit not 16, but 56KHz. It has not so much benefit, because, at that time we don't have any tracker program, which was capable to replay 56KHz samples.
Maybe A1000 can't do this, we had ECS machines, but AGA not required.
