Budget Cables for Budget setup - pls advise

Hi all!

After weeks of research and auditioning have settled on the following kit -

My 1st Speaker Setup

Speakers: PSB Alpha B1
Amp: NAD 316BEE
DAC: HRT Music Streamer II
Source: Macbook Pro
Cables: ? (USB cable, Interconnect, Speaker Cable)

As you can see I need help with cables. My gear is really beer budget stuff so nothing too fancy. Just need cables that are decent enough for such an affordable system.

Total budget for cables: 100USD for all - USB, Interconnect, Speaker Cable =(

Many thanks in advance!
