BWs are good speakers. What is the new model retailing at these days in India.
They used to command quite a premium a few years ago.
BTW, you don't need to jump the gun on external power amp, unless you are absolutely convinced the AVR can't drive the speakers.
For movies, you'll have a sub running and the AVR has 70% guarantee. For 2Ch SR5013 has a respectable 100Wpc FTC spec.
So why the hurry. Get the AVR/speakers/sub sorted out and then hunt for extra power (after hearing only the AVR at your home).
