A new EIM help

Hi, back in August I purchased a Hifi-Man RE800 Silver to see if I liked them better than my Sen 600 headphones. Well I was blown away! I loved the inside your head sound instead of the on your ears sound of a headphone. The bass was actually there with the RE800. I always felt the Senheiser 600 had weak bass (nothing deep or punchy). I soon learned about "V-shaped" sound. So I figure I'm looking for an upgrade to my RE800' that will still have the same overall sound, but only better. Naturally I have considered the RE 2000 Silver, and it's near the top of my list, but I am concerned about the comfort. My shopping list so far is:

HifiMan RE2000 Silver

Campfire Audio Andromeda 2020

Sure 846

FiiO FH9

In today's Covid conscious world, I'm afraid I won't be able to audition without purchasing. My budget is around $1,000 +/-. I'm hesitant to buy so many, only to send all but 1 back. I want to be WOWed all over again, or should I just keep using the RE800 (which are now reduced to $149) ? My source is my Hi-Fi system only, which is an Auralic Aeries G1 to a Schiit Yiggy MiL DAC, then off to a Benchmark HPA4. Please any guidance would help a lot.
