I think the Mac fear would add a nice bit of warmth to the T3's, but not the level of detail and speed as some of the others. The 350.8 is a very nice amp that I think would work quite well with the T3's. The BAT I think is one of the most versatile. It has a level of warmth, detail, dynamics and Bass control that I think would help you get the most from your speakers.
What kind of music do you listen to most? I think rock would favor the BAT, with it being a toss-up between the Pass and BAT on other kinds of music. If you favor dynamics detail and like a bit of neutral warmth, go with BAT. If you like a bit more warmth with a bit less emphasis on dynamics and speed, than you might favor the Pass. Either way you probably couldn't go wrong.
BAT has amazing customer service btw. You can call and talk to any of the 2 principals, Viktor or Steve anytime. They really stand behind all their products.
Good luck! 👍
