Chord Hugo is a $2500 product 🙄. Cobalt is a portable and you can get better alternatives for this like TempoTec Sonata E44 which is 79 bucks.
I like the 789 for IEMs and full size headphones (not many THX based amplifiers support IEMs like 789) and desktop setup with SU-8s.
The below recommendations from Andy vault.
1 TempoTec Sonata E44
2 Ovidius B1 Apogee Groove
3 Hidizs S9 Pro E1DA 9038SG3
4 Astell & Kern PEE51 Hidizs S9

If you own a chord hugo there's not really a reason to buy this imo. You could connect the Hugo output to the amp since the Hugo is very transparent, and you can gain the sonic properties of this amp. But most people probably want to keep the transparent output of the Hugo or go into a tube amp.

Chord Hugo has a very good but not state of the art DAC. The THX aaa 789 doesn't have a DAC. The Chord Hugo has a good headphone amp. The THX has a great and far more powerful headphone amp with cleaner sound.
Chord is great stuff, and is likely not worth replacing, but the THX headphone amps are better.
At the same time, I bet 99.9% of people wouldn't know the difference.

Yes, assuming you have a decent source/dac.
If the source is flawed, this will just make it louder.

Yes, I use it to power both hd6xx and 58 jubilee

Get the THX if:
- You can't get enough volume out of the atom. The THX is necessary to get more volume (gain, not power) out of some inefficient planar headphones.
- You have interference issues. I had (mostly insignificant) interference from my monitor that was solved by running a balanced topping D10-balanced. When I ran the atom, I had to be careful about placement near my computer monitor and its wires.
- You want to run the 4-pin balanced headphone output for more volume.
- You want a really solid feeling amp. The all metal build just looks and feels great.
DONT get it for sound quality. I couldn't tell the difference between the THX and the Atom when volume matched with a multimeter and the measurements on audio science review support this. Basically anything above 90dB dynamic range/SINAD will sound identical, so this is why most people say put your money into good headphones as a priority.Benchmark your ears here: http://www.klippel.de/listeningtest
The best I can distinguish is about -39dB using sensitive IEMS and my thx 789, and I usually get around -33dB. After 39dB, I just don't care anymore. Compare that to a dynamic range of 110dB or higher for these amps and DAC's. We are living in the golden age of audio thats for sure. I hope this helps.

Like the other USB-C DAC/AMP combos listed from Andy - nothing beats the portability and small convenience of these smaller USB-C devices.
They may have a premium cost but it sure beats being forced to listen to your headphones near an outlet where the amp is plugged into.
USB-C devices are able to be plugged into phones/laptops allowing the user to listen to their music/videos anywhere

I just want to add, I believe atom has more power single ended than 789 (I looked it up when I was buying the atom)

As someone else said, invest in great headphones. Try out good amps or look for amps that bring out the qualities of your headphones that you bought them for, not the other way around.
would i benefit by changing my hd6xx to balanced xlr cables?

Before pulling the trigger on audio gear check out the measurements at AudioScience.com. For example. the Atom measures better than the 789:

The output specs manufactures use (i.e. 6000mW) are usually taken right at the clipping x-point. Distortion climbs exponentially just before reaching this threshold.
