The other side of the coin (pun intended) being if I can afford a $30K set of speakers and the necessary additional gear needed to propel them I would probably start looking for a house-(unless I'm in a New York, San Fran,Hong Kong, type surrounding).
When I was with my first wife I had my MG1.6's in our first place a 900 sqft condo. That lasted about a year when told her we needed a bigger place. Fortunately it was during a the 2003 housing boom where we bought it for $250K and precisely a year later sold it for $350K, minus the penalties that allowed us to find a 3 bdrm 1600 sqft house with a 14x40' Sun room that ended up being my music room.
