Get out and listen to as much gear as you can. What else are you to do while you wait for your house to be built? Congratulations on the retirement!
Even though you can afford a $100k rig, you might find that $20 or even $15k worth of gear is just as good to your ears. The systems that receive BOS awards are often near the $20k range. If I had a $100k budget, I'd spend a few $000 in road trips to demo as much as I can. You have the time and the scratch, you don't need advice here. Listen for yourself.
