AHI's quality isn't great on paula. It's really meant for sound cards, and the paula driver was just for compatibility (since <5% of Amiga users actually had a sound card when AHI was released).
A hint to increase sound quality on AmiNetRadio: use a Stereo++ mode, and whatever you do, avoid the direct DMA mode. It sucks. Also try to get a decent sample rate, over 28kHz if you can.
And did you know that you don't actually have to use AHI in AMPlifier? Use directaudio if it bothers you!
