Pretty much all the cards from the Sound Blaster 16 have a line-out. Many have both, line-out and speaker ports. Some have a jumper to disable the amplifier. The AWE64 (I think it's called value) has also got line-out and speaker.
After having had quite a few Sound Cards I do however start to feel that this is a little bit of a myth because the noise is part of the signal, doesn't matter if it's amplified or not. And at some stage you are going to amplify it anyway (powered speakers or dedicated Amp) and then the signal (and noise) gets amplified anyway.
The AWE64 Gold is simply a card with very little noise and this has nothing to do with the line-out. There are Sound Blaster 16 cards with line-out that are terribly noisy. So picking a quiet card is the real task here. ESS Audio Drive or PCI cards tend to also be pretty quiet.
