Many seem to be talking about their last system .

I am over 50, this has nothing to do with the answer. Until perhaps you are 95.
Brayeagle, your dedication to music and sound is admirable.

I don't plan on upgrading only repairing or replacing if some componet dies before I do. 

We can die at any moment, probability unknown. What is the point of taking it into consideration ?

It is much more than funds. First, I have to 'see' this new system. In other words, formula first numbers will follow. See the sound then find the components to make it. Second, availability. And finally, it must be 'politically' right, including the timing. There are other projects and expenses.
