I got to that point some years ago after picking up my Sophia 2's. Now, it's just replacing things that break. My Meridian 557 amps I loved, died, one by one, and aren't repairable (Meridian tried, but parts are obsolete). Tried a number replacements then settled on a Meridian G55 I run bridged. Happy again!
There are a lot better sounding systems out there, but retirement beckons, and they just aren't worth the money when I'm happy with what I have, and the ears are definitely not improving with age :-)
