The fun of improving audio equipment by small but effective changes
The chronicle of this successful DIY-Project and a suggested roadmap for upgrading I just realized; it is already 10 years ago I designed the first version of the DDDAC1794! So, I thought it to be a good idea to write a short chronicle of the DDDAC history. The DDDAC1794 which is still available as…
Today Tests What’s on the menu today? A short meal this time, but hopefully as interesting as short 🙂 “JĂĽrgens” Clock – with thanks to Mamal from Berlin Listening to the possible impact of power supply to the Andrea Clock JĂĽrgens Clock Mamal from Berlin wrote me an email after reading the earlier posts…
The test goes on… This time mostly thanks to Stefan Wapstra, who was so kind to send me three 45Mhz Clocks. The First version of Andrea’s DRIXO Driscoll clock PCB, a Crystek CCHD-957-25 and the standard Clock delivered with the FiFoPi Q3. Next to those I had the Accusilicon Clocks 318 and 338 warmed…
Follow up from the earlier Post! In the earlier post I went into a lot of detail on this topic, so you might want to refer this post as well. In this second part I wanted to compare the new Accusilicon 338. I now finally received these with the Chinese parcel service but still…
More background on this special DDDAC output transformer (OPT) Already in the very early days of the DDDAC I wanted to be able to use the PCM1794 to it full content in Mono Mode by means of an OPT. This would give the following benefits: Effectively doubling the number of DACs (like doubling the…
