Class D

[Supernova]

I see a lot of people have the hate on for Class D amplifiers in various forums. I have been looking into nCore NC500's or Pascal's and was curious why it's such a touchy subject. I have some A/B amps and a class D amp and like them both. I've never heard a class A or tube amp. I've read somewhere the class D takes a sign wave and turns it into essentially a square wave to amplify the volume and then back into a signwave and therefor the original sound is not the same. I know this is extremely simplified explanation and not even close to the entire picture, but the general idea.

Can anyway point to some very good sources that really break down the differences in the amps? Does class D really change the source? I thought I'd post in these forums because people seem to not be quite as hostile to the subject and I've seen some very good write-ups and analysis on various products.

A lot of (most?) early Class D amps sounded awful because they were cheap amps. If you spent the money there were good ones out there. That certainly wasn't unique to Class D.I have a .pdf that explains it pretty well, but the 260 kb file exceeds the attachment limit of the forum. Maybe a mod can help me out on this?

Tried emailing you but didn't get through, Lee. Sent you a PM as well.

Didn't get a PM. I'll check with a mod.

Alaric, your email address is bouncing messages back. You should update your profile to a current email address.

I'll bump the attachment size limit up, once I figure out how. EDIT: Ok, it's now 2 MB per attachment. This forum has been around a while, and 10 years ago the limits were reasonable. Now, not so much.

Cool... I thought the uploading pictures features was a bit archaic, but no biggie.

We'll try this, and I'll get on the email issue.

Edit: Email fixed. The forum had my old one. Doh!
