Cypress Hill

My Dad has the Pro media 2.1 and it sounds amazing when listening to mp3, movies or whatsoever! i'm planning on upgrading my sound too, but not for Mp3 but for my Console gaming{PS2} and sometimes DC, now i've heard that DTS should be really cool for ps2 games especially the game GTA:Vice City... my dad recommends me to get pro media , but does it support DD/and or DTS? i just have to know which sound setup i should get for my ps2...
