Hello! I have a pair of HSU Research HB-1 Horn Bookshelf Speakers + VTF-2 Mk4 Sub.

I use a Macbook, which has a relatively inferior soundcard/DAC. Should I buy an extra amp and/or DAC? If so, are there any recommendations for the 2.1 system I listed above? I listen mostly to electronic, trance, deep bass, etc. sort of music.

I have a good budget, not in the thousands range, but flexible.
