Default David Broadhurst Dac site address?

Does anyone know the site of David Broadhurst and his DAC design?

I have found some other threads but the site that they point to does not work.

Thank you

George

Thank you,

This site has only pictures. I would like to get more documentation on this project. Is someone selling pcb's for this Dac? Where?

Thanks again
George

Default You Found Me

Hi Folks,

That would be me who you're looking for.
My website hasn't been up and running for some time now although I am planning to restart it with a pre-ampllifier design....

I'm not offering PCBs for my old DAC design however I have attached the schematics of what is the latest revision of the design.

Cheers,

David

Thumbs up Great !

Maybe I should finish mine...and tweak it...
It is really finished, but never boxed, as Peter D said long time ago, he did not like his. I have since understood that I don't share his "sound" (non-os)...

David, I'll get this when I click on your www button:
Sorry, the page you requested was not found.

EDIT: was not up, I'll get it.

The reason why I ask is because I have you listed at my linkpage and somebody reported the bad link.

Hi Arne,

The design I have just posted has a revised analog stage otherwise it would be the same as the one you have built.
I agree that the asynchronous sample rate converter in the CS8420 is probably the first thing that should be upgraded.

Peter D was actually pretty happy with the DAC but has sinced moved to Non-oversampling designs (I think). Anyway he performed several upgrades to the power supply (seperate supplies for the analog and digital sections of the DAC chips themselves). He said this "It moves the sound of an already fine DAC to the next level."

By the way I have found over the years that the socket the DF1704 is mounted in can sometimes give problems. You just need to push it down so that the contacts rewipe against the pins of the DF1704.

peranders,

Thanks for providing a link to my website, I am hoping to restart it again in a couple of months once I have this pre-amp design ready.
