I didn't increase main filter capacitors. They have identical capacitance, only voltage is higher (from 50V to 63V and from 25V to 50V) because I couldn't get any others with those exact capacitance. I'm aware that in general there is no problem using higher voltages and capacitance, but it may sometimes cause problems if you go way too high. Deviating values a bit doesn't harm anything, but going way higher may do so, like replacing original 4700uF with 10.000uF capacitors.
It went nuts because something was wrong on PCB, possibly a solder debris bridging some gap either on OP-AMP or the loose main stage capacitor (that was my mistake since I didn't make sure it' soldered perfectly). This is a DIY project with what I have at home. The solder tool is nowhere near professional, I don't even have OP AMP 8 point de-solder attachment or even basic weave to remove solder. It was all improvised.
As for the sounding "brighter", maybe I didn't use correct words, but describing sound is hard anyway. After replacing main stage capacitors with basically same values, just much better quality and replacing main satellites OP-AMP with way higher quality one, I can really hear more details and sound has changed for the better. I called it "brighter", one could call it "more detailed". I always thought these caps changes are bullshit and they don't change anything, it's just placebo effect because you expect it to change because you used expensive Japanese audio capacitors, you expect it to be better by default. So, my expectations were already zero, but I did it anyway because I was curious about it. But there is a difference and I was legit shocked how it actually changed the quality for the better whether that's good for circuitry life span or not. Plus, it was a nice lesson by working on tight circuitry. So far I've only been replacing components on large empty PCB's using big ass solder tool we used to have. You didn't even have to be precise, they were that empty. I've fixed few things so far with such DIY fixes. One was Creative's soundcard, another one was LCD monitor with swollen and leaking capacitors. This one was not out of necessity, it was out of curiosity. Gotta learn things somewhere. I've spent 50-60€ on more stupid things than this. Way more stupid, so it's fine
