funny thing.....i loaded a bunch of Ownhammer IR's in the Epsi in no particular order just to see which cabinet i liked without knowing which cabinet i was listening to, i was surprised that i liked different cabinet than i would normally use.

i loaded up 2-3 of each speaker studio vintage mixes (my preference because they are warmer) and it was actually easier to pick out good IR's because i wasn't thinking about which speaker i would normally use.
