Can anybody gives a cliff note version of its definition and difference to what's otherwise available? thanks in advance...
I am sorry, I have no opinion on the matter. I am sure you do. So, don't mind me, I just want to talk audio and pie.

I asked my brother in law a similar question and here's the response (Class D are also referred to as digital):
"The primary difference between classes of amplifiers is their
transistor/circuit topography.
Class A amplifiers use transistors that are continually biased (on),
resulting in very low distortion, low output impedance, but high (relatively) current consumption.
In the case of Class A low distortion is, to some degree, achieved at the cost of lower efficiency.
Class D amplifiers use transistors that act as switching devices. Consequently their power consumption is much lower, and produce somewhat more distortion.
Class A amplifiers are often preferred by stereo buffs because they claim they sound better. Class D amplifiers are commonly found in portable devices where power consumption
is a prime concern. There are also Class B, C, and E amplifiers, each with their particular features and applications, as well as hybrid AB, BC, etc, classes."
I know it doesn't exactly anser your question, but it should give you some additional info.There is no genuine justice in any scheme of feeding and coddling the loafer whose only ponderable energies are devoted wholly to reproduction. Nine-tenths of the rights he bellows for are really privileges and he does nothing to deserve them. We not only acquired a vast population of morons, we have inculcated all morons, old or young, with the doctrine that the decent and industrious people of the country are bound to support them for all time.-Menkin -
jdhdiggs, thanks for the explanation. It helps! I am curious since Sony has just released a new ES line that employ this technology..I am sorry, I have no opinion on the matter. I am sure you do. So, don't mind me, I just want to talk audio and pie.

doest H/K have a receiver thats all digital?

Polkatese - You mean the TA-E9000ES? That is a very nice piece of equipment for sure. Most of the ES line is being redone, receivers and the 777ES SACD player specifically.CTC BBQ Amplifier, Sonic Frontiers Line3 Pre-Amplifier and Wadia 581 SACD player. Speakers? Always changing but for now, Mission Argonauts I picked up for $50 bucks, mint.

doro,

I am curious when I read something like Direct Digital Amplifier...is that a true class or marketing hype kinda statement? They look very sleek indeed...I am sorry, I have no opinion on the matter. I am sure you do. So, don't mind me, I just want to talk audio and pie. -
Yep, that be them. The TOTL receiver replaces the STR-DA7ES, and so on. They have more power per and are all 7 channel w/ ability for 9.1? Sheesh, just what I need....9.1, screw that, I would be broke.. I think they are doing the right thing with 7 channel standard. All manu's are probably going to go that route.
Honestly I don't know Sony to create "hype" about the ES line, beings they can't hype anything w/ the regular line either
The line is very solid.
Sony has always created their own version of new technology, so I guess that in a way could be considered hype...I am not sure.CTC BBQ Amplifier, Sonic Frontiers Line3 Pre-Amplifier and Wadia 581 SACD player. Speakers? Always changing but for now, Mission Argonauts I picked up for $50 bucks, mint. -
SONY IS CRAP -- ES is not -- SONY......SUCKS -- ES DOES NOT...;)- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.
