DACs, streaming, re-clocking, Raspberry PI
Introduction I spent most of the past year working on a follow-up for the good old (10 years) DDDAC1794-PBT. I promised this would be available for DIY as well and here it is! An introduction story for the DAC and for the Dual Power Supply which is designed to go together with the DAC…
Introduction It is in the name DDDAC… I have spent so many years on DACs, it was about time to follow up on my curiosity on R2R ladder DACs. Not the ones inside a chip – we know them well in the meantime – but the discrete ones. A decade or so ago, very…
UPDATE February 4th, 2024 Dear DDDAC Fans, Feb 4th. The Boards are back from the SMD Assembly. I will test if all is 100% and than the kits will be prepared by Audio Creative and shipped out to the customers. I have made a few extra boards, if you are still interested, send me…
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…
Final clock upgrade for my DDDAC This is supposed to be the last and “final” blog about clocks. In the previous parts I did a lot of testing and reviews on all kind of oscillators for use in a DAC and for use with Ian Canada FiFoPi and Reclocker (The reclockPI). Ultimately, for me…
NewClassD Neutron Star 3 Clock Daniel from Berlin was so kind to send me this summer (yes sorry for late response and post !) his newly acquired NewClassD Neutron Star 3 Clock for comparison with the Andrea TWTMC (The Well Tempered Master Clock). The comparison was not 100% apples and apples as this was…
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…
Introduction Inspired by the many reports on the audiophile improvements when using UltraCaps (or super capacitors) in Audio applications, I decided it was time to start looking into this subject myself. For starters I wanted do some tests with it on my own DDDAC. Of course I am also interested in the technical aspects…
I started using this Blog-Site subdomain from dddac.com to blog my audio adventures 🙂 I will be starting to post here several topics and projects. As I have some projects done in the past, it will not be all very chronological, but more what I like to show for now – It will be…
