Arcam AVR400 - Def Tech 7002...good cable match??

Hi - new to the forums...On a limited budget of $500 total for Speaker cable and interconnects for my system. Arcam AVR 400, Arcam CD93, Oppo BP103 blue ray and Def Tech 7002....I need 8 feet for speakers and 1m for Cd will be fine....any thoughts?

I have an Arcam avr400 as well and love it, I was using Straightwire and switched to Morrow Audio cables they made a huge difference for me, they do have used cables for sale on their website.
good luck
