I have made my dac power supply around LM317 as a preregulator and after that TL431. Dac is CS8412/TDA1543 based. Passive i/v. Three power supplies. Been listening it for a while doing all kind of mod's. It is working quite nice now.
The point is that today I have implemented today Sulzer regulator (scaled down to 7V) as a power supply for the TDA chip. These little things are VERY nice dac's. Just let them work. Please connect them to the best power supply that You can think/pay/build. I can't tell You how my dac is working now- You have to liesten to it.
Just let them work....
