How to improve sound quality when using an android device for music playback.

[eldene]

I have two powered speakers ,and would like to know which route to go to get the best out of these speakers by using my cell phone or tablet without having to use a DJ mixer or controller?
I am willing to spend about R2000.00
Thank you in advance
