Thanks for the Welcome!
Eric, I honestly am just getting off the ground, so I haven't tried many, and I can't entirely remember which headphones I've used for each. I wanted to get out to RMAF-Canjam this year, but I have to work unfortunately. Pretty much everything I encounter now, I try with the HD800 if possible. Here's the (literal) short list. Note the absence of TOTL amps:
Bottlehead Crack w/Speedball
Decware Taboo MKII
Glenn OTL
Maverick Audio D1 (owned/sold)
SPL Phonitor
Schiit Valhalla 2 (owned/returned)
Schiit Asgard
Schiit Mojo
Woo Audio WA7 (own)
Woo Audio WA6
