integrated /seperates step down


I've been pondering a simplification of my system. I am running Cary 2a3-se monoblocks with the Cary SLP-88 preamp. Would the Rogue Tempest Magnum, Jadis Reference Orchestra or similar be stepping down?

I realized that this might have been a vague question.

Would the switch likely disappoint? Has anyone switched from seperates like this to integrated and felt an improvement?
Please expound. Personal experience?

I have to admit that the balance and bass/treble controls concern me, but I have heard great things.
