Wow, such a very thoughtful and detailed post, BlindJim - good on ya!
I used to have a Butler TDB-5150 (*great* amp, BTW) and used the trigger output from my Emotiva UMC-1 to power on/off the Butler. IIRC, I had no problems getting the Butler to respond to the UMC-1's triggers. The UMC-1 requires that the 3.5 mm connector/cable be a mono one, NOT stereo. So you might want to investigate and see if the Integra also has this requirement.
Additionally, (most of) the Integras allow you to adjust the trigger's delay. You might want to experiment with increasing the delay from 1-2 sec. to 3-4 sec. This may not have much effect since the Butler does have a "soft start" feature which limits startup inrush current - but it couldn't hurt to experiment....
Good Luck,
