DIY Non-OS TDA1543 DAC
I need help form you guys out there who have done this project before. I finished my mini-DAC non-OS CS8412 and TDA1543 project. The sound is very revealing with very vivid vocals. At first, I was very impressed with the sound then I noticed that the highs rolls-off at certain frequency. I manage to get back the highs but buy putting a resonant ckt at the output. Now it's lacking the punch (bass) and the soundstage is narrow compared to normal CDP.
If anybody can suggest how to get a beeter bass and wider sounstage then this project can be called very succesful.
BTW, I used solen 2.2µF output caps and Hovland 0.1µF input caps. The I/V resistor was changed to 1.5K and Vref to 1K.
Need some inputs here.

Any advise/recommendation is highly appreciated.
