If you don't plan to use any other source, while I rarely agree with George (and his comments about tube coloration are really off the mark), in this case it does not seem to make a lot of sense to employ a preamp.
Now if you have to have long interconnects between the amp and the volume control, a preamp might be in order, or if you plan to have more sources. But your CDP has a volume control, you might just try hooking it up directly. As best I can make out, that is part of its design.
