Soliciting some friendly advice.

I plan on purchasing the Panasonic Sa Xr70/DVD S97 system. My question is, should I also be looking to add a separate CD player, such as a 5 disk changer? I have heard that when playing CD's thru a DVD player you experience somewhat of a delay in the unit reading the disk. If adding a separate CD player is benificial can anyone recommend a high end 5 disk unit?
