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 !

My most important Projects on this Site:


Modular n x 12-parallel non oversampling DAC with asynchrone XO re-clocking
and SPDIF and USB to I2S-bus conversion !

The DDDAC1543 project is finished !!

A directly coupled Stax Electrostatic Headphone Tube Amplifier

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 !!!!



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"!



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"!



Active ETON powered "NON-ported" Subwoofer

I decided to construct a MASTER SUB Woofer, to only support the last octave with a power full low bass.......
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 !!!!
