I would like to bump sound quality for my computer headphones.
Is there any good circuit for amplifier or even DAC that does not cost a fortune?
Or maybe... is it possible to get a ready to solder KIT?
or should I forget it and get external sound card?
p.s. I use bose QC25 now. They falling apart and will need to be replaced at some point, but it is the most comfortable headphones I ever had. I always work with them on, even without any music playing. Helps me to concentrate.
Any recommendation for replacement?
