Most of us dont like change for the change if we are not reviewer or professional sellers...
We are here to improve for the best what we own...
We are here to learn about acoustics and controls of electrical and mechanical parameters (tweaks and method and devices )
Obsessive compulsive disorder is not fun...
Purchasing race may be fun for sometime , but is not a useful hobby for those like me who want MUSICAL best possible acoustic experience for our budget limits...
Buying one piece after the other compared to the creativity implied in installing a system in a room , is like masturbation compared to making love with a loved one...
We listen music not the gear once a system/room is created ... It is my hobby...
I’m not sure the OP is not satisfied, it seems he just likes change, very different...
