Thank you all for your input. The reason I asked the question is I just recently borrowed some different speaker cables and I'm in the process of evaluating those and the differences they might be bringing to the table. I didn't want to add 2 new variables at once. When I feel I have an idea of what the cables are doing I will introduce the CD player to the system. I just thought that while I wasn't using it I might just throw some burn in time on it. Its nice when people can simply answer the question that was asked, and not interject their biases.
