Ok... So I took it to the tech today (Third Coast Guitar Repair- in Chicago if you want to know). We plugged it into two amps, an Acoustasonic and a Deluxe Reverb... and no hum except for some extra gain when the volume was cranked.
It's funny because I plugged it in to my system again this morning and the hum had greatly abated. You heard the recording, so I'm not making this all up. I wonder what could have caused the noise? Loose ground wire somewhere?

My vote would be a minor plating imperfection on the guitar's output jack. The next time it hums try pulling the cable out and reinserting it a few times.

I had two 914s from March this year (latest version of ES2) and they both had ground loop hum. This issue combined with the fact the newest ES2 is SO sensitive made me return them.
It's a shame because if it wasn't for this I'd say the ES2 is one of the best systems on the market.

On a side note, I totally agree with my experience of the latest ES2, it picks up EVERY noise on the guitar. I don't have experience with the pre September 2016 version.

Update- Check this out- I used a DURACELL battery!
I'm not sure how I stumbled on this YouTube link, but perhaps this solves the mystery of hum/no-hum. If you watch the video it explains how this guy was experiencing hum that was caused by battery misalignment. It could very well be that the Duracell I had in the holder misaligned for the recording, then after removing and replacing to see if it had a full charge, it realigned itself and made most of the hum go away. The only thing that kept me from feeling like an idiot before was that I got a recording of the hum which is undeniable.
Check this out.... Link in case you can't watch the vid through the forum app https://www.youtube.com/watch?v=40j3OpS76nM

There are numerous reasons for hum with any electronic system. You should always try the instrument with a different cable, through a different amp or mixer etc. or different location. New battery as well. My band played a couple of weeks ago and my tube amp had a big hum. I unplugged my guitar and the amp was humming on its own. I was about to swap out the tubes and noticed I had my iPhone charging and I had placed it under the amp head on top of my speaker cab. I moved the phone and the hum was gone. Stuff happens. You should trouble shoot yourself before going through the bother of trying to return/fix.

BTW, thanks for following up. Some folks don't bother once the problem is solved.

Any update on this thread from OP?
Also it could be a blown fuse. There is an easily replaceable fuse in the battery compartment and you can buy them through the Taylor website.

The hum going away after reseating the battery may just have been a coincidence. I have an Epiphone Masterbilt DR500 and like the original ES system, it has both magnetic and bridge sensing components to the sound. I was getting occasional hum. When it would come, I couldn't get rid of it. When it was gone it was solidly gone. I eventually traced it down to the fact that the Nanomag pickup on the Epiphone was really sensitive to humming from any nearby transformers. What it was was my cell phone charger. When I (or anyone else) was plugging in a cell phone charger into the same AC breakout box, or even one nearby, I would get hum. Otherwise I was ok. Boss effects chargers also seem to do it. I had any number of theories before I figured it out. Now, I know what to do. Your situation might be different. I am suspicious though because batteries are DC. They shouldn't hum no matter what you do, good connection or not.

One scenario I can think of with the cell phone is that you had it plugged in nearby and it was charging, and giving you hum over the magnetic component of your ES system. Then when your cell phone was fully charged, it stopped drawing AC current and the hum stopped. Maybe it just dropped down to a trickle and the hum just mostly went away. I don't know, maybe I am off base, but I am skeptical about battery seating causing hum.

Be that as it may... You heard the hum in the recording. I didn't make it up. But like magic, it went away. Did my gig on Friday and no hum. Ok. I'll take no hum. So perplexing. Maybe it was the Duracell battery that came installed with the guitar that I popped out and popped back in? BTW... Another oddity is that Taylor's battey cartridge (holder) size. I'm going to have to post that one separately.
