Thanks again. One more question kung ok lang. In your experience what capacitors including the series name have you tried and can recommend? I've only tried mostly Panasonic kasi.
Panasonic FC is a favorite among diy'ers because of their high ripple rejection and low impedance. But the thing is they have magnetic steel leads (like Rubycon ZAs) as compared to the ofc used in audio grade caps.
For general use Elna Stargets are ok pero hanggang 1,000uF/16v lang available sa RS Components. For digital decoupling, nothing beats Sanyo Os-con (Organic semi-conductor) yung SG series na pang audio. Limited values na lang available sa Farnell because they are discontinued. Pwede na din yung SP series. Suitable for audio din it uses OFC.
Just remember na yung converter and dac chips have an analog ang digital supply. So use the os-con for the digital supply and the starget (Black gate gamit ko dun sa analog supply ng dac) for the analog supply. I also use BG for op-amp supply decoupling. FK kung kasya pero kung hindi kahit Standard pwede na.
Some people remove the coupling cap after the op-amp. Didn't do this as I believe that they are there for a purpose, to block any dc current from the op-amp. Pwede Starget dito pero I use Elna Silmic (silk fibers in the dielectric) in my cdp.
Never use a low esr cap after a regulator. Bypass your power supply diodes (ultra-fast, soft recovery diodes) and large value caps with ceramic caps (preferably yung X7R type).
