Have you ever moved to improve your system

didn't move to improve it but listening room was a huge factor in choosing a new home when i moved for other reasons

Not moved to suit my stereo, but selected my apartment based on reproduction of sound quality. I went from a 13' by 31' (Living room foyer) listening room with a hardwood floor and CONCRETE underneath to a 12' by 21' with a all wood floor underneath. Over time you get used to it, but at times I miss the bass.

I moved from an apartment into a house when I was in college - not so much for room acoustics, but so I could play my stereo without neighbors complaining. That was 30 years ago, and since then I've never considered multi-unit housing for this reason. In the last 30 years I've moved 6 times, and selection of the house always has considered room config/dimensions. In the last 8 years I've built 2 dedicated listening rooms in my basement, and am working on a home theater (it's a big basement) down there now. I probably would have stopped with one room if not for Audiogon.
