1st check out if your power amplifier can be used with passive preamp.
Power amp shoud have high gain and high sencitivity.
CD player have to swing with ~3V output voltage for ideal case and input sencitivity of your amp shoud be ~0.6V
Also check input impedance of your power amp. It has to be at least 47kOhm.
