You are probably better off in the Class D section with that quest.

What exactly do you mean by digital amplifier? A class-D (which is a switching analog amp) or a 'true' digital amp where you amplify digital values/numbers and then do a D>A?

Default Pure Digital amplifier is...

Pure Digital amplifier accept only digital signal(pcm and i2s format). but D-Class accept the analog audio signal. I don't want to tell what is more better for us, but in my case i love the pure digital amplifier.
In pure digital amplifer, we can control volume, eq, tone control, and Etc. with digitally. It's one of merits, I think.
Come on, Let's DIY

So, basically, you're talking about a DSP, followed by some kind of power output stage?
Maybe before starting diy we should know WHAT we want to diy

Jan Didden is right, But we started to discuss..But I had expericen to make the full digital amplifier, so I'd like to listen many idea, but I am first thinking to use Digital Pre Amplifier + Digital Powe Amplifier.

Digital Pre Amplifier is PULSUS's DDC
Digital Power amplifier is TI's TAS5142.

Looking at your your website it looks like you ask us to help design an amp that you wish to sell on-line?

Dear Jan Didden.

No Way, Because I don't sell digital amplifier. I don't have any idea to sell digital amp on my website. I am always design DA Converter or Pre-Amplifier, not power amplifier. ^^
I just want to make digital amp with people oversea. That's the reason.
Buf If you think so, just keep watching my website forward...
Anyway Thank you for your advise.^^
