This is a very subjective issue, with varying opinions and points. In my opinion based on
testing, listening and measuring, it is beneficial to have a good sized cable, say 12 gauge. This will not
impede or restrict the output. You can find this cable at Home Depot, etc. If you want a low
cost brand name, Monster is popular. There are numerous brands at all price points. You
should also have good quality interconnects (between amp and CD).
If your system is well balanced, and I would not limit the potential by using bargain basement,
or "throw in" cables and connectors.
