I agree with Khokugo. Having said that most newer integrated amps are just a power amp with a passive pre.
I think the decision as to whether to get separates or an integrated largely comes down to power requirements. If it's 60w per channel or less then an integrated is probably OK, if 100s of watts then separates are probably required.
Interesting that noone mentioned the relative importance of long interconnects versus long speaker cables. One of the advantages touted for monoblocks is that the monoblocks can be placed by the speakers, with the preamp driving a long interconnect. This is apparently better than having long speaker cables, because the long cable is carrying very little current, almost just a pure voltage signal.
