Did some more "testing" this AM. I have a short delay and a longer delay dialed in on the DM. It sounds fantastic. I pulled it out of the mix and put the FM3 in it's place in the loop for delays/verbs and some modulations. The difference is non-existent as far as immediacy and variety of effects and associated tones. The quality is just as good to my ears but probably because I am a digital delay guy at heart.
I think I am rotating to my usual POV of analog up front, digital in the loop. I could go on a extravagant digital delay rabbit hole but the FM(s) are already here and sound glorious. I think I am just as well off putting the FM3 on the board with the analog drives and chorus and being good to go. Oh my god I have went full Gasp
