Apart from the downsizing issue, which for me is not relevant, I think downgrading your expectations can be profitable and free your mind to concentrate on the music.
When you always search for the 'best', within your budget of course, you remain fixed on the sound of your system. If you were to intentionally select components for synergy alone, i.e. 'I like the sound and that is good enough', you can relax and focus on the music. You know there are better components out there that could sound better. Could......but then you no longer care. Yours is good enough. The only thing you really lose is bragging rights.
That is what I've done anyway. Works for me. Oh, when I do feel audio anxiety approaching I try to tweak my room and set up. Occasionally I think I actually improve the system/room interface enough to have made it worth while and it costs $0. :-)
