I think I do have a ".edu" address provided by my uni, but gotta ask my friends how to access it first, never log in before

Any opamps you would recommend? Hehe... What about the big fat power filter cap? Looks kinda expensive though.
You could try LM4562, LME49720 or LME49723. All of them are nearli identical, on paper at least, the 49723 have slightly worse spec. What I liked the most is LME49720, 2nd is 49723 and lastly 4562 (this is vary)
But for SB046X (XtremeMusic, Fatal1ty, XtremeGamer Fatal1ty) only supplies 5V to the opamp, its not enough to unleash its full power. Recomended voltage is 15V from one guy statement, I tested 5V and 12V and the latter indeed have better and smoother sound (you can ignore if you dont understand this, it'll work anyway

)
About power caps, you can use any general purpose caps, like Rubycon YXA. Just don't use ultra low ESR caps like Sanyo OS-CON, the regulator will make a buzzing noise because of it
This is my final back layout of analog out, its hard to route negative supply, positive supply and ground on small area like that

I have some problems before get the final layout (note,
green = ground, white = positive, bue = negative) I need to shield them though, there is some noise at full volume, but music is very quiet enough
