I was able to find specs on your amp (47k ohm input impedance/1.4V sensitivity) but not complete specs on your player (I could only find it has 2V output). Given what I have found and based on the designers minimum requirements, if your player's output impedance is less than 200 ohms, a Lightspeed attenuator would be worth trying. Given its cost of roughly $500, you don't have much to lose.
Not all passive preamps, in fact probably very few would be an ideal match in your system. Instead, you can always try an active buffer. There are many fine ones within your budget including the Pass B1, Horn Shoppe Truth, and the tube unit from Dodd Audio. These will have low enough output impedance to drive lowish input impedance amps. You should also have no issue connecting your source to it, but just in case you may want to verify the input impedance of the buffer.
