I've never come across one of those before; I like it.Twenty years ago (or thereabouts) Sharp marketed what they called a 'digital' integrated amp. Class D with built in 1-bit DSD. Sporting a kind of Jet Jaguar Tokyo-modern aesthetic. Normally I'm not attracted to that sort of space-age design, but in this case I thought it was kind of interesting, and not unappealing.
Although it looked like a toy, the company wanted $15,000.00 for delivery, which certainly had to be a non-starter in the general hi-fi marketplace. That said, one thing it had going for it was that it looked just as cool upside down as right-side up. Few integrated amplifiers could make that claim.

Wikipedia, your and everyone else's friend:look guys, I'm not a egghead science major like some of you. I have a hard enough time remembering what a transistor does
what's a mosfet? what's a rail?.linear gain devices ?.pulse width, pulse density, or related techniques to encode the audio input into a pulse train?..whatWikipedia, your and everyone else's friend:
A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. Transistors are one of the basic building blocks of modern electronics.[1] It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal

A class-D amplifier or switching amplifier is an electronic amplifier in which the amplifying devices (transistors, usually MOSFETs) operate as electronic switches, and not as linear gain devices as in other amplifiers. They operate by rapidly switching back and forth between the supply rails, being fed by a modulator using pulse width, pulse density, or related techniques to encode the audio input into a pulse train.

At the time Sharp was known in the US (and still is) as a maker of microwave ovens, and other small appliances you'd find in a big box store. Earlier, in the '70s or so, they had a mid-level range of hi-fi gear, marketed under the Optonica name. I don't think there was much of anything to distinguish Optonica from any of the other more well-known Japanese makers. It was just 'there' on the dealer's shelf, taking space, and if it sold before Pioneer, Sansui, Marantz, et al it was no doubt because of a heady discount.I've never come across one of those before; I like it. I can't read what I assume is Japanese, but it looks really nicely built: http://amp8.com/tr-amp/sharp/sm-sx100.htm
Well, if you want to learn, there is not much else to do but to read.what's a mosfet? what's a rail?.linear gain devices ?.pulse width, pulse density, or related techniques to encode the audio input into a pulse train?..what
it's hard for me to keep it all straight with the fatigue of congestive heart failure . seriously
I divide my life between pre heart attacks and post heart attacks, triple bypass, congestive heart failure, etc. . A world of difference in concentration and fatigue. A trip to the front door to get a 10 pound box can result in a two hour napWell, if you want to learn, there is not much else to do but to read.
If you are not in the Matrix.
But why are you learning something that makes you stressed? Ignore learning the technical aspects of how amplifiers work. Listen to and enjoy music instead.I divide my life between pre heart attacks and post heart attacks, triple bypass, congestive heart failure, etc. .

I have no idea how a simple post that started this thread turned into the perception that i wanted to learn technical things. It was just a simple questionBut why are you learning something that makes you stressed? Ignore learning the technical aspects of how amplifiers work. Listen to and enjoy music instead.
Then the main advantage of Class D and its improvement is this: High-power is available from small and lightweight packages.I divide my life between pre heart attacks and post heart attacks, triple bypass, congestive heart failure, etc. .

Okay, your first post in the thread.Answer. Probably not. Then you should probably step up a little more,regarding amplifier. .How big an audible difference now it would make for you? I do not know.ask some simple questions like my first post, which was really just a curiosity.
Make that 18 years! Mine is about 15 years old, should still end up on the left part in the amp charts I guess.Hypex UcD launched what, 10+ years ago?
