You ever think about building a room and setting it up as a reference listening space professionally? Might be worth looking into. You can afford it and there are very talented design people in Cali.
Every other month you drop a few K on the hobby. You totally deserve a good room as a canvas to play in.
. To be fair your room may sound great.... but I betcha your gear is not your bottleneck.
Great dynamics means a clear separation between the range of sounds near the noise floor of your room to the extent of human hearing of over 100db. The best thing you can do to improve dynamic range is lower the average room noise floor of your room by decreasing decay times.
Getting loud cleanly is relatively easy. Getting back to quiet quickly and in a controlled way should be as equally important. It is cheaper and easier on your hearing too!
