Are digital amps better?

hey, I was curious how and why digital amps are better? I hear that they draw less power from your battery and help with dimming headlights.are there any other good things about them? I hear they have no need for a dac since they are all digital?

They're not really "digital" amps, they still have an analog output...

Digital amps = Marketing hype

Well, unless you have a fiber optic output on your head unit running to a fiber optic processor that in turn runs fiber optic outputs to your amplifiers. Then again, why would one want to spend all that $$ in something that has a 60 decibel, or greater, noise floor at highway speeds is beyond me....

I would run optical if I could, Im so sick of noise problems (you may or may not have seen my noise issue threads which NO ONE had any advice on)

No such thing as a digital amp //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Class-D amps, however, are more efficient.

The first ones were horrible, now there are small power full range SQ amps, and very good high power ones, hehe.

"Digital" (class D) amplifiers use a technology that produces a sine wave with the peak and the trough cut flat. So if you use it for full range audio there will be audible distortion compared to other designs. However, the boards are designed so they draw less current so they don't get hot or require as heavy a power feed. They are ideal for powering sub woofers because at those frequencies the human ear cannot discern the distortion in the sine waves.
