Cable suggestions? Opinions needed...

I'm looking for ICs and speaker cable for my first good system... I know next to nothing about this! I have Green Mountain Audio 1.5 speakers & a Rogue Tempest Magnum integrated. I assume neutral cables would be best, no? I was thinking about DH Labs & Zu (maybe Zu Julian spk cables & DH Labs BL-1 Mk 2 ics). I'd appreciate any input I can get. TIA.

Also, any opinions on DH Labs D-75 digital cable?
