cable shopping...Help!

I'm looking to buy a couple new cables for my system. I need a cable between my preamp and amp and I need a cable for my DAC to preamp. I'm considering some of the "budget" cables I see here on this site. I curious about Bettercables, Homegrownaudio, The Music Company, Phoneix Gold. My system is Marantz cdp, Denon DAC, Rotel preamp (I sometimes use it passive), Golden Tube SE-40 amp, and Triangle Titus xs speakers. Any thoughts would be appreciated.
