your hearing is far too sensitive

You should educate yourself on Supreme Audio

Look around and find some 100W transformer, center tapped

destroy some chips before you get the right way

then you should educate yourself on Supreme Audio

Maybe your ears don't like chip encapsulated solid state,
maybe you'll like discrete transistors

But if you educate yourself on Supreme Audio

Maybe youll find that tube amplifiers and old vinyls are the only ones
that bring you satisfaction

Happens ...

Im no audiophile, my tda2003 usb powered sounds fine,but that just distorts so much even at less than 1w
Btw i have some vinils from my mom but i cant use them,i mostly listen to dubstep(dont hate me!),and some oldies

So i got a phone chrarger and i hooked it up to my once powerful tda 8560 and made it into a small amp for my laptop so my tda2003 can be sent to the tv which also needs some good audio,the charger is 9v 800ma and i did 15000uf cap to reduce voltage sag,which is still a big deal,i got some leds hooked up to it to light my room up and the dim with the bass
