Class D is just Dandy!

1 - Direct Digital

@erik_squires FWIW the phrase above is a marketing thing. It means that the amp has a DAC as its input, but the amp itself is actually analog, like all class D amps are. IMO/IME marketing terms like this tend to confuse the marketplace.

@tomcarr ’PWM’ stands for Pulse Width Modulation.
Such an amplifier usually has something like a triangle wave oscillator in it. The incoming audio is compared to the triangle wave and this determines how long the output devices are either on or off. The switching frequency (which is otherwise determined by the frequency of the oscillator) is then stripped from the resulting signal and what’s left is the audio.

@atmasphere , thank you Ralph.

So, with all of this Class D talk, where to the new ATI 52X and 54X rate in the scheme of sound quality? I have read great articles saying how wonderful they are but what about people who have actual experience with them who don’t work for a paid magazine?

In a home theater application will there really be much difference than say running an older parasound or anthem amp?

Thinking of buying the d3020 for my daughter's room and pairing with a pair of epos els3.
Sources would be a tt as I see the v2 now has a mm phono input and a PS3 via toslink.

Do you have the v2?
