Welcome to my Home Page for high resolution audio projects
Welcome to my freshly styled WEB Site. In the past year I have been working on a
huge project: designing a DAC which will play 192kHz / 24bit material from a PC (or Mac...)
There are many DACs who can do this, but I wanted to make sure to design a NOS version,
as so far, every listening test proved, that this actually leads to a more open, natural and detailed sound.
I found this to be possible by using the well known PCM1794 and avoiding the digital filtering.
This proved to be VERY tricky, but I managed to find the tricks to do it.
It has been a great adventure with much to learn and a fantastic result in the end....
I like to suggest, you start with the special pages I created for this project.
You will find the button at the TOP LEFT of this page...
As an author of this Site and the very well known (now called Vintage) www.dddac.de Site,
I hope you will have as much pleasure, reading about my projects
as I have had, designing and building them. You can find many
audiophile (tubes and more) equipment and accessories. I will describe all activities in
detail and try to make it easy for everyone to use (part of) my experience. No
secrets! Everything can be found on the "Download and Link" pages! (see Button above)
My hobby results are available for everyone. Without other enthusiasts on the WEB, I never would have
come so far.... keep checking my site and enjoy reading and building!

2016 April UPDATE: NEW...
Revised DAC Module Board with Tentlabs Shunt regulator
for analog section and FET current source for the "Pin 20" bias
Finally ready.... Two important sound quality improvements, based on broad experience of the DIY community, are now implemented in the new DAC board module:
The embedded Tent shunt is for the 8Volt only. The 3,3V stays LF33, with option to mount a shunt replacement (for those who really want to do this.
My tests showed that the 8V does the most improvement and honestly I could not hear true difference on the 3,3Volt...
- Embedded, under licence a Tentlabs Shunt regular, on the DAC board for the analog supply voltage (8Volt)
- Embedded a FET constant current source for "PIN 20". Nice improvement of sound quality. On top a clever way to easily adjust the bias
And of course totally back wards compatible with mainboards and old dacs (you could even use them mixed if you want)
