Thank you all for the help. I think i must go and test some stereo amplifiers integrate and see what will give out. But one more thing, you guys, you think this speakers(DALI Opticon 6) "deserves" an expensive amplifier(about $2500-3000)? I mean i will have, speaking in percentages, at least 40% more quality sound? Cause if i will go for one. I ask that, cause I'm pretty sure, once to audience will be a think, cause of acoustic treatment of the room, and once back to my home will be another thing :) \n\nBest regards.
