When sizing an isolation transformer, it is important to know the peak power (worst case) of all componants which will be attached and then multiply that by 2-3 times. Source componants such as a CD player vary very little with music levels, however, your amp may have an instantaneous peak power level of more than twice the level with no input.
While you can put selected componants on different isos, there is in general no advantage over using one properly sized for all. The one exception is you might consider putting the digital componants (i.e., CD) on a second smaller iso to keep them from contaminating the rest of the componants.
If you look at my system, you will see architecture and wiring diagrams of how I did this.
