I see your point here.

So for example, when MAD Max/MAD Newton plays a MP3 stream encoded at
22Khz, 24Kbps mono, the program (or the Newton sound hardware) is really
downsampling it to 5kbps? Do I read this right?

I'm not expecting anything stellar here. If I want good sounding MP3s I'll
buy an iPod. I just think it's neat that with the Newton + Ethernet,
HTTPlib, MAD Max and Mad Newton I can play MP3 streams off the 'net with no
additonal hardware required. I just wonder if there isn't room for
improvement with the speaker itself. It's easy enough to try once I find a
speaker that'll fit. The theory is interesting, but it's so easy to
experiment I think I'll just try it and see what the results are!

Thanks very much for the information & suggestions.
