Good!
The sense of hearing is quiet, powerful, and monitoring. It would be better if the power adapter can be upgraded.

Good sound, bad volume nob
As the topic says, really like the amp but as some have had the problem with the volume nob so do I. It started to make a scratching sound in about 11 o'clock after couple weeks. Really irritating but not gonna ship from Finland back to States because of it.

Sounds great
Clean sounding very neutral. Loads of power Its nice to have a component not impart sound of its own, so you can hear sound of DAC or Headphones

Clean Amp
Before I had the ifi Zen DAC V2 paired with the HD6XX which I thought was good already but lacking power. So I bought this and paired it with the Zen DAC V2 and yes more power but with extra features like the TrueBass feature provided with the Zen Dac as HD6XX sounds quite flat already. Although the Sundaras are different pairs of cans I think the TrueBass feature on the Zen DAC and this amp makes it sound quite close to the sundaras, except it's still lacking soundstage. With that being said the HD6XX IMO will still be the gold standard for a while especially for its price and when paired with this amp.

Clear and detailed but...
I will definitely be an outlier in this review chain. I currently have a Schiit Fulla which I have been using for many years and enjoyed the clean not fatiguing sound. Since I wanted to upgrade my set up I looked at several amps including the 789, xduoo TA10R, and the Zen Signature. I took the leap and bought the 789. I paired the 789 with my HD6xx and used the DAC out of the Schiit Fulla. The sound quality of the 789 demonstrated exceptionally clear notes with very good separation of instruments. The sound stage was not as broad as I would have expected. My main critique of this amp is that after 20min of listening, I started to experience fatigue and could not listen anymore. I repeated the listening session a day later and experienced the same thing. I enjoy listening to a broad range of music and classical seemed the best with this amp followed by jazz with vocals, however, modern music from pop, electronic, and rock was too busy and fatiguing. Unfortunately, I had to return the amp. Perhaps my 50-year-old ears would be better served by a tube amp.

While I do not own this amp, I own both a Monoprise Monolith DAC/AMP with my new foray into becoming an Audiofile with digital music and headphones. I also picked up a new TA10R along with a Genalex Gold Lion Tube. Of course, we all have the HD6xx, but I also recently picked up the MassDrop Focal Elex cans. I can tell you that I love listening to soundtrack music, Hans Zimmer in particular with this TA10R over the Monolith DAC/AMP. To your point after about an hour, I feel very fatigued, especially with the HD6xx's on the Monolith. However, I can tolerate music much much longer on the TA10R with the Elex cans with little to no fatigue. HD6xx's are very much more tolerable as well on that hybrid DAC/AMP. I also just ordered a Topping D70s which I've paired with an xDuoo-MT604. I'm looking forward to that paring. Some thoughts from 53 year old wanna be Audiophile.

Just Buy it
Just Buy it. Its basically a standard at this point to have this amplifier. You also really don't need anything else if you don't want to get into the weeds for amplification. Just Buy this and a good tube amp and you're covered. Just pair with a nice DAC and its an endgame setup for most people. Its more than worth the price especially if its on sale

Loud, Clear sound
My first amplifier, I wanted something well balanced to power my new HD6XX and 99 Noir cans. The sound production is clean, and while I did have to source a DAC separately, I am 100% pleased with this!

Transparent amp with plenty of power. Way smaller than I imagined 😅
