Once In A While
My systems have gone thru spurts over my lifetime.
I will go thru a buying frenzy to put together something I've been planning over a period of time. Then unless some new desired tech comes along it can remain static for many years. Last system up north before my retirement had remained static for over 15 years. The subwoofers surrounds were going bad and needing repairs by that point. LOL
Sold off everything to move down here and put together a quick n dirty cheap receiver based system while I thought things over. Then another frenzy of purchasing components to get my current rig going.
Now when I'm in the mood to tweak I'll fool around doing some measurements with the UMIK-1 mike I got some time back and Audyssey, REW, and AcourateDRC software. If I ever make myself believe I can do a much improved job of DRC with a miniDRC box over what I'm getting now with my tweaked Audyssey XT, I may go that route but that's no major $ investment in any case.
Swaying back n forth between the miniDSP box and a new Ruger Charger pistol to play at the range with. Boys and their Toys.
