  1. Hi, for my opinion, don´t expect too much from Ultracaps and LiFePO4. We allready use that since 2014. At first i loke the idea only to listen Music out of a big cap without beeing connected to the wall. But in a direct comperision the ultracaps and the LiFePO4 lwere only second place behind a good regulated psu. I have tried a lot of battery/Lipo/LiFePo4/Ultracaps up to 3000F cells during the last 25 years of Hifi - i was never satisfied. The same with lt3045 Regulators. i really dont understand the Hype. Its a low ripple, ok, but the soundquality is only midclass. Everytime, when i use them the Sound seems to be thin for my ears. Kind regards Sunny
  2. @rafa there are only 2 transformers. This is allready a compromise. Normally i use one transformator per psu. What you are pointing at is a differential mode choke. This is part of every psu i build. For the last 4 years i build a lot more than 40 different psu with different designs vom battery to ultracap vom choke incl. to shunt back and forth. In a high end psu you can try your very best to work against some of the more than 30 different kind of noise. Every transformator produces cm-noise. Therefore a cm-choke in the ac line is included. The hammond choke helps against hf-trash and differential mode noise. The big audible difference is the mosfet recitiver. Every kind of diode sounds different - from glass to schottky. I used differend kinds of zobel during the years. But this mosfet stuff is a big step in sound. Clearer and more dynamics than any other. Space is not my problem.... If you would see my dacs. 😉 I never would use a ssd. Compare hdd, sdd, msata, sd, usb stick an cf and let your ears decide... Every part has a different power and that's importent. Best regards
  3. Hi, did anyone tried daphile in a client/server setup and compare it to audiolinux? for the last nearly 4 years i am using daphile an the futro 900 thinclient with realy supreme audio results. i use it in an Server/Client Setup with my own designed power supply. To try daphile its only a 5 Minute thing to do... You just need to prepare 2 usb sticks or sd-cards to make it run. anyone here who tried that too? you can buy my recommended futro for 20-30 euro on eBay - and even when labled Fujitsu its still made in Germany! Its a perfect match for the daphile 64-bit rt kernel. 4GB ram is highly recommended. Throw the 20v smps and use a good and clean min. 2A rated LPS for optimal results. On the picture os my prototype client. Newclassd neutron star reference clock. DC filter, mosfet rectifier with lt4320, choke filter and belleson and uwb2 regulators. Seperate power for thin, cf, clock and a modified ideon 3R MK2. A bit small the enclosure... But its ok... regards sunny
  4. There are a lot more problems. The easiest way is to use a pc hardware that doesn't need a fan like the fujitsu futro ones. Its a computer with a high audio performance. Best regards Sunny

    DIY DC power cables

    Hello, it took me 1,5 days to read this thread. Wow, so much to say about DC-Cable. Now i came to the Point were I need a little bit help from you. At the moment i am building a amplifier with the newclassd singularity 2 modules. i need to use 2 enclosures if i want it to look nice to the rest of my hifi stuff. Lars Clausen is doing that too in his singularity cookbook v3. https://www.newclassd.com/NCDCOOKBOOK300.pdf (i took one of his pics, to make clear how it should look like). He recommended to use awg 12-14 silver plated copper to connect the caps close to the rectifier and the big big caps close to the amplifier module. That means i don´t have only a +/- cable. I need +/gnd/-. Any idea how to build this in starquad? two lines? one positive/gnd and negative gnd? Forget starquad - use 3 wires awg 12-14? shielded or not? I see a benefit from starquad in this connection - thx and regards sunny
