I use a Fiio BTR5 and it powers them just fine. Was worried that I'd have to find a new BT/USB DAC but that's not been the case.

On low gain using the 2.5mm balanced output I'm getting ~105db with the vol at about 40/60. I've turned it up louder for a few sec just to test and couldn't hear any distortion.

And the BTR5 would be considered a wimp compared to Gryphon and most other recommendations!....?...

Yep.
I've got a desktop amp with more power but it sounds the same to my ears.

Not an expert but, unlike a dynamic, planar drivers tend to (always?) have a flat impedance so they don't require more power to have the proper bass response.

This old article is a good read on the subject:

And here's a power calc showing what would be needed to drive the E3s at 110db:

Demo request..If u haven't yet,. Can you talk a walk around outside , down the street, see if it's a comfortable experience? On the bus.. Ha. Thanks

This is where they get the most use.

Walked around the office a bit with them but they're a bit big to be used outside IMO.

If I want to listen to something while out and about I have wireless buds and IEMs.

Vnice...I'll give you 10 bucks to do it. But you have to make detailed observations on "strange looks count" . Lol...

I think it should be 115db given its bass boost.

CDC warns that hearing loss is possible with less than 5 minutes of exposure to 110db

Here is a great review that compares the Stealth and the E3. English subtitles available.

Another review compares the Stealth and the Expanse.

Would the chord mojo 2 be better than the M1 macbook output for portable use/production?

iFi Gryphon has more options. Do not use macbook. Chord is fine but usability is better with the Gryphon.

I'm looking for whichever has the best performance and power, I don't need various options.

Either will work. You need to look at specs and reviews and make the decision. It’s rare that anyone will say this is the best because it depends and no one wants the burden of your purchase.

Why don’t you find something easier to drive such as 660S2?

I see no point in suggesting an entirely different headphone when I'm asking about amps, however I'll stop asking on here and try to figure it out on my own

 

[chesebert]

If all you are looking for is to make sound from E3 then either headphone jack or mojo2 will work. You will hear a fraction of what E3 is capable of. Don't complain if you don't hear the visceral bass impact, sub bass extension and boundless soundstage and high resolution rendition of atmosphere, among other things.

I personally don't understand why people intentionally gimp their high end cans with meh electronics. They would almost always be better off with mid priced cans and top electronics.
