Class D is just Dandy!
I thought it was time we had a pro- Class D thread. There's plenty of threads about comparisons, or detractors of Class D.
That's fine, you don't have to like Class D amps, and if you don't please go participate on one of those threads.
For those of us who are very happy and excited about having musical, capable amps that we can afford to keep on 24/7 and don't require large spaces to put them in, this thread is for you.
Please share your experiences with class D amps!

And then without their output filter, the input wave form will be unrecognizable from the output, because of the HF garbage, and melt your tweeters silently in a nano second.The operating principle of a class D amplifier is that it uses a filter to eliminate the switching waveform from the output. In this manner Class D shares the function of the filter used at the output of the Berning amplifiers. In either case, this is part of the operating principle and can't be separated out; the idea that anyone would run one without the filter is ludicrous. |

the idea that anyone would run one without the filter is ludicrous. Your scare mongering. No one said run or listen to class-D without the output filter, it said to "look" at it. Whichimplied to see it on a scope as that’s what was being discussed, comparing input wave form to output wave form, far from the same or what your implying. For those that wish to see what goes in and what comes out between Class-D v Linear amplification which is closer to the original input, or closer to "straight wire with gain" as what was the start of this Test input:1khz perfect square wave http://www.tronola.com/moorepage/Sine/1kHzsquare.jpg Output: Class-D: https://www.stereophile.com/images/archivesart/406Halfig01.jpg Output:Linear Amp: https://www.stereophile.com/images/archivesart/999A565fig2.jpg |
