Advice on switching to separates

Currently using an Exposure 2010s integrated amp with Harbeth mini monitors. I am absolutely satisfied with the overall performance but have always been wanting to try separates. My question is can i better my integrated with separates on a budget of around 1500 dollars. I also have Omega super 6 Alnicos speakers from a second system which was scrapped. Due to space limitations I now use the Harbeths because they are smaller, but they can be switched back in if I can put together a system that beats the one I currently have. Any suggestions or should I be happy with what I have. Thanks.
