There is not a single piece of commercially available gear I have that I could say that I would never sell. I do have a pair of custom built pair of Fried C3L with D2 woofer modules that my dad and I built from solid black walnut a couple of years ago. Although they are not cosmetically perfect, they sound pretty damn good and are never, ever going anywhere other than with me for as long as I am alive. Nothing will displace spending that time with him and creating them together.
