Agree with most above.
I built what I call a mid-fi room with a $15,000 budget (and was able to buybthriugh a local dealer at about 60% of internet retail which I think is normal).
Since that point my top end budget has changed. But I really have little interest in upgrading. It’s a great room for me. Instead I have scratched the upgradis itch by building two new setup in my office and in my formal living room against a WAF.
This is an industry of light assembly, tried and true engineering, and heavy markting.
