Your no-name cables already sound the same as high-end cables, no need to add anything (except maybe some blingy sleeves, ferrite beads, and such). 
Seriously, if you want better sound, upgrade your speakers, or maybe simply using better encoded audio files could help as well. A headphone amp in between the sound card and the speakers won't do anything good.
