How to choose cables for my system

I would suggest DiMarzio M-path interconnects and Super M-path speaker cables. You can find them on Headphone.com and on DiMarzio website though I am not sure that he sells directly. That's under $1000 for all cables. They are very good, I use M-path interconnect.
There are also much cheaper cables sold here on Audiogon: Anti-Cables, JW Audio, Mogami and others.
DiMarzio cables are made mostly for professional applications and should work well with just about any equipment and speakers.
Just remember that you don't want cables to be longer than needed. You might also want to try some aftermarket power cords.

He doesn't want to play with cables at the moment. He is new to the US and has more important things to do. The man just wants good relatavely inexpensive cables to start playing music. To set it and forget it for at least couple of years.
In any case, new and often used cables too need break-in time to sound best. Don't judge the cable's performance based on how it sounds first 50-100 hours though good cable will not sound like junk even the first minute of play. Some cable manufacturers, like Purist Audio, say 200 hours is needed for a cable to open up completely. I am sure it varies from brand to brand and perhaps even from model to model.
