Thanks for you replay Maynard!
1) I don't listen at very loud levels as i live in an apartment . I listen mostly to Rock, Blues, Fusion and Contemporary Jazz.
2) The size of the room is roughly 35-40 square meters. My sweet place is in front of the speakers forming almost equilateral triangle with 2.75m side.
3) The room contains a lot of furniture but many smooth surfaces are also there. Here are some photos of my apartment link. The speakers on the images are Infinity's which are now replaced by the Klipsch's.
4) I prefer warmer and smooth sound but not too much laid back. I know that Klipsch speakers are known to be opposite (bright and forward) but decided to give them a try as no other speaker can provide such a details, vocals and cymbals.
5 )I'm located in South-East Europe and i don't have the opportunity to listen and return back
As i said, I really enjoy the current setup but i miss a bit of boost in the lower frequencies.
