Looking for ic

Hi I'm looking to purchase some reasonably priced ic for my first hi fi. System consists of
 MARANTZ PM6006 
MARANTZ  CD6006 
MARANTZ  NA6005 
REGA P1
MONITOR AUDIO BRONZE 6

Any suggestions will be appreciated.  Also the recommended power for the speakers is from 40 to 150 watts the pm6006 outputs 45wpc is this enough to drive them or would I need to think about upgrading to a more powerful amp?
 Thank you
Dave
