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!

George,

You've repeated the same 2-3 points on this thread, over a dozen times, with basically the same set of logical debunking happening immediately afterwards.

Are you offended if I ask you to go make your own thread to bash Class D?

Thanks,


Erik

Hi @georgehifi

It is not appropriate to use an oscilloscope to measure the audibility of signals. If you are having trouble using one, I suggest going to an electronics forum to help ensure you are using it correctly, and are not connecting it in a way that leads to incorrect results.


Best,


Erik

I just replaced a Schiit Vidar with a Parasound Zonemaster 2305 and find it a great addition to my system (and I really like the Vidar!).

I can’t speak to the technology points being raised however for myself Class D gives me a level of performance that I could never afford in a Class A, A/B amp.

So while not perfect, however when compared to a similarly priced Class A amp a well implemented Class D seems to me to be a significant improvement.

JA used his high order special testing output filters because he didn't yet have the Audio Precision's auxiliary AUX-0025
That's right,  what I said and why you can't see much switching noise on the square waves Without those "special testing filters" the square wave will look like this https://cdn.stereophile.com/images/1212AM1fig02.jpg
Sorry it's is you that needs to get some tutoring on this, as I said the output filter limits bandwidth and also because it's a low order creates phase shift down into the audible frequencies.
