i've had to down size due to moving a lot, smaller spaces, financial reasons when my daughter got into an expensive university. every time it was a rebuild but with age comes experience and I've found satisfying music in all sorts of price points and I've found you don't always need to spend big bucks to get enjoyable music.
one thing i've recently found is higher efficiency can get you closer to bliss for less money if you don't need or can't use the lowest bass (can't use as in condo-loft-apartment).
