Sneek Preview --->>>
www.dddac.com 
My new WEB Site is definitively NOT ready yet, but there is already a clear storyline and framework on what will come, as well circuits of my new 192/24 USB NOS DAC for download. I am working on this daily and I look forward to complete this site within the next few weeks.
Please have a look and let me know what you think ! send me an email at: mail@dddac.com


Author's note:    

I hope you will have as much pleasure, reading my WEB Site, as I have had, designing and building my audio equipment. First this site was only covering my DIY DAC project. In the meantime I have been building other audiophile (Tube !) equipment and accessories. I will describe all activities in detail and try to make it easy for every one to use (part of) my experience. No secrets ! every thing can be found on the download pages ! My hobby results are available for everyone. Without other enthusiasts on the WEB, I never would have come so far....  I must admit, that I am not updating that frequently (work, work, work...), but there is a lot in the pipeline, so keep checking my site and enjoy reading and building !

Doubted a long time. I was not sure whether it would be a good idea to do Home Cinema stuff on this Site... But why not?? It is a nice DIY project, with speaker design, Filter design, Lots of construction work and the most important, LOTS and LOTS of fun afterwards !!!!

 

 

TUMOS
Sensational new MOSFET power amplifier with real Tube sound!!

TUMOS more or less started as a small experiment, with as unexpected as surprising results......
This Project is finished now, check the "Other Projects" under the "Tube Portal"!

 

 

ETAMSAS
ETON Air Motion Satellite System

Based on the great experience with ETON Chassis (DD Master SUB), I decided to construct a Satellite Loudspeaker, based on the existing HGP Model ..... This Project is completely finished now, Filter design took many months and is completed now.
This Project is finished now, check the "Other Projects" under the "Tube Portal"!

 

 

DD MASTER SUB
Active ETON powered "NON-ported" Subwoofer

This is the final result, check the "Other Projects" under the "Tube Portal"!

A huge portion of this site covers the "DDDAC 2000", where it all started with! I will give you detailed descriptions on how it all works and why I came to this design.
Voila!    Proudly presenting the DDDAC 2000, with peek inside...

 

Happy Listening and Building !!!!
