Just looked at your pictures. Nice apartment, nice furniture, gorgeous view! Unfortunately, none of that helps you with how your system should sound. If you really want to get the best from your investment, you will need to:
1. Use a dedicated listening room
2. Use Jim Smith's book Get Better Sound
3. Use room treatment
4. Set up your speakers and listening seat for best sound
I know most others won't/can't do those steps, but the truth is you will never get the best sound with compromises. The room/setup will give you at least 50% of what you will hear.
