I admit that I haven't any idea. Yes, headphone output is higher than line
level. After flogging the crap out of creative labs website (bletcherous,
idiot web site), I see that the "speaker" output isn't. It's a line-out.
The Altecs have an input sensitivity of 300mV, and about a 10Kohms input
impedance. I don't know what that means WRT their ability to handle higher
level outputs. I don't know if there's overload protection.

I had really assumed line-level would be available.
