In your situation less-likely you have problems running long interconnects from your CD-player. 2ft between pre and power is ideal and the input sencitivity is ideal. There is no CD-player that I know of has an output less than 1V which is in your case ideal as well.
So you'll best with passive preamp and even with upgrades toward different more higher quality passive preamps.
