I'll count this one as a "holiday" gift, given that my birthday falls into what is called the "holiday season."
About 6 years ago I moved into a new place with my then-girlfriend. We fought for a while about how to set of the living room, with me preferring a setup that led to better placement of the front speakers, and no stupid coffee table between the listening position and the loudspeakers. We ended up compromising (speakers set up along a different wall at the right height and orientation, but coffee table in front of the couch, no subwoofer in a room corner though considering my ULF at the time was coming from a closed box Ava18 powered by a Crown XTi2000, placement wasn't a huge factor) but neither one of us was happy with the way it looked (or sounded), truth be told.
That year, I woke up on my birthday...and found the living room arranged the way I had originally wanted it, with the front three speakers optimally placed and the coffee table banished to the side where it belonged. Obviously, I needed to tweak here and there (hide wires better, set levels, recalibrate the multisub system for the new subwoofer locations, etc.)
It didn't cost her a cent, except for lost sleep. But it was by far the best-sounding gift I've ever received.
