Compact speakers: Energy vs. Canton vs. Harman/Kardon vs. Mirage

Hi,

This is my first post here. I have searched the internets for days before finally making up my mind and actually asking here.

I currently have the following setup:

Onkyo TX-NR609
Front: Klipsch Icon V VF35
Back: Klipsch Icon V VB15
Sub: Sony cheapo Best Buy clearance.

While I very much like the Icon V, they are too big for my new living room setup and I have decided to sell them and replace everything with a compact speaker kit. Budget under $600 preferred...

I have a few options:

Energy 5.1 Take Classic ($400) Specs here: http://www.energy-speakers.com/home-theater-systems/?sku=TK-CLASSI-5-1
Canton Movie 85 CX ($350) older version of the Movie 90: http://www.canton.de/en/homecinema/movie/produkt/movie90.htm
Canton Movie 125 MX ($500) older version of the Movie 130: http://www.canton.de/en/homecinema/movie/produkt/movie130.htm
Harman Kardon HKTS 20BQ ($550) Specs here: http://www.harmankardon.com/estore/hk/us/products/HKTS-20/HKTS%2020_HK_US?skuId=HKTS%2020BQ_HK_US&searchMode=regularProductOnly
Mirage Nanosat 5.1 ($500) specs here: http://www.miragespeakers.com/products/nanosat-series/?sku=NANO-SAT-5-1

Obviously I'm open to other suggestions if I have missed any other brands or models.

Thanks a lot!
