I am new on the forum this being my first post. I am also new at the sound game as you probably can tell by my question. Here it is: I have a Rotel system with their entre level amp and preamp, a RC 1070 and a RB 1050. The speakers are Klipsch bookshelf, 75's. The system is in a small den, about 10x10. I have wondered if I increased the size of my amp would I improve the overall sound of the system? I like what I now have but feel that it lacks a fullness, a feeling of presence, that I would like to acheive. Any help or suggestions would be appreciated. Jack
