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

I have this and had a JDS Atom.
Updated to a balanced DAC and cables to match.
Difference was not worth the hundreds of dollars invested.
Money is far better spent on headphones.
This is an amp, not a DAC.
Yep, a pretty good one.

Can this be comparable to Chord Hugo or Cobalt portable headphone amp/DACs?

BTW for anyone clicking on this: you gotta remove the equals sign from the end of the URL to get it to load properly. Issue I've noticed with links to the Audio Science Review forums.

I have Hugo first version and Mojo, Hugo is the clear winner more refined. I wanted to ask..Can this be comparable to Mojo or Cobalt?
Chord Mojo is good but this with a good Dac gives better quality of the sound (I used to have Chord Mojo and it is dead now}). Cobalt is not the same league of 789. It is not even better than portable dac/ amps I have mentioned in my previous message.

what are these four pronged inputs and outputs i've been seeing on these amplifiers? i've always been used to just the analog inputs where you could plug banana plugs into
