What is your budget for new speakers?
I say speakers first because, while not typical, some speakers have special needs (IOW, the AVR selection is best done when you know what speakers you will drive).
One significant shortcoming of Gene's recommended systems is he needs to use MSRP for his pricing.
Often the best options involve special discounts!
One of my favorites are the JBL Studio 5 Series which is discounted around 5 times per year by about 50%!
The are competitive speakers at full price, but when deeply discounted, I feel they are no-brainers if they fit your budget!
I just checked and they are, indeed currently on sale as follows:
JBL Studio 590 for $500/ea (MSRP=$1000) (check dimensions and that these will fit your room! They are likely bigger than you think!)
The JBL® Studio 590 floorstanding loudspeaker brings professional-quality sound to the home experience. The Studio 590 uses the technology that JBL engineers developed for pro-audio loudspeakers to deliver accurate, powerful sound to your living room. The Studio 590 is a perfect complement to...

JBL Studio 570 for $200/ea. (MSRP=$600)(a smaller sized version of the 590, I have not heard these, but they should be fine for handing off bass to your Speedwoofers, JBL uses good drivers in this series and I am familiar with the 530 bookshelf which uses the same 5-1/4 inch woofer)
JBL Studio 570 floorstanding loudspeaker delivers robust sound at a professional level and can work with multiple power amplifiers and fit any home decor.

JBL Studio 520 Center for $190/ea (MSRP=$350)
Amazon.com: JBL Studio 520CBK 2-Way Dual 4-Inch Center Channel Speaker: Electronics

Do a little research on these, but if they fit your budget, I don't think you can find better!
Unfortunately, JBL is not showing when the sale will end, so either be fairly quick or willing to wait a couple of months if you are interested!
As far as surrounds, they do not need to match as much as the front 3.
However, I firmly believe in more or less ignoring the surrounds in the interest of getting the front 3 you want.
Stick with the Miccas for now.
Then, you can wait until the 530's go on sale for $300 - 350/pr. (they are not currently on discount)!
On the other hand, it is hard to recommend the 530's for surrounds if you can get a pair of 570's for $400! That mainly depends on if you have room to use tower speakers as your surrounds!
