1st System - Help with cables

Hi Everyone,
I'm in the process of putting together my 1st quality audio system. At this point it consists of; Simaudio Moon I-5 Integ Amp, Rega Jupiter cdp (on the way) and Dynaudio 1.3 mk2 speakers on dyn stands. It's taken me quite a while to research and choose these products and I wound up purchasing each through Audiogon classifieds.

Now I just have to get speaker cables and interconnects.I'm mainly focusing on the speaker cables and would like to find something in the $300 or so used range that would be a decent starter/baseline cable for this system. Something transparent that won't add any uncessary color to the sound. Since I haven't used the system yet I can't say that I'm looking for a cable that will alter the sound in any particular way. I can always look for that later after I've had extended listening time and develop some preferences.

Any suggestions would be very helpful as the choices are pretty overwhelming. Thanks for the help...

John
