Can you shed some light on why you are starting over? That is a scary prospect to me and I would not want to do that. I especially would not want to have to choose new speakers. But then I am very pleased with my current system. You must have some good reason for changing unless you have commitment problems.
I am not trying to be critical. What I am getting at is what about your present system dissatisfies you so much you would scrap it all and start over? If you tell us what equipment you have and what you like and do not like about it I think the responses would be more informed and therefore more helpful to you. What are you looking for but not getting from your current system?
Good luck.
