If you have the wall space, build or have someone build you some shallow, narrow built-in bookcases. You can use cheap wood and stain it cherry or spring for real cherry. My brother built some for me one weekend out of pine, I painted them white to match the wall, and I can now store about 3000 CDs on the back wall of my listening room, well behind my speakers. I had him make the bottom shelf double-tall so LPs could fit in. It looks really good and cost about $425, labor and materials included.
