Hi everybody! I need some help. I'm building my first HT. I want to buy a decent amplifier and basic speakers. Later on I will update my speakers. I will build a 5.1 -system. My living room size will be 18 square meters. The ratio between movies and music would be around 70%:30%. I have searched several forums and I've ended up with these amps: - H/K avr 230 - Yamaha RX-V650 - Sony STR-DB790QS (European model) NOW. I need Your advice. Which model would You select and why? Please tell me your own experiences rather than what you've heard... Thanks!
