Great sound, impressive build, and 3 gain settings
For reference I’ve been using this amp with the drop ifi zen signature DAC and HD6XXs since the beginning of July. This amp sounds very crisp, a bit analytical, if you’re looking for a very warm amp this isn’t it. The build quality is exceptional, it feels very solid and sturdy. Nice buttons and knobs too. I also have the drop ifi zen can signature 6xx amp and I must say if you have HD6XXs and only those, the ifi is the better amp for that purpose alone. But the thx is great at driving sensitive iems to big demanding headphones. Also just for the fun of it, i tried this amp with my turn table (thorens td160) with the Schiit phono preamp, and it made for a very nice sound, especially on records made in the present day where you don’t want super rich amplification. I got this amp for $150, but even at $200 I’d highly recommend it.

If you can grab one of these for 150 or less, this is a steal! If not, this is a great amplifier, crystal clear and with plenty of power. But there are more options out there that worths consideration.

$150 well spent
It looks pretty good and feels high quality except the scratchy volume knob. It comes with a nice cloth pouch that I find very useful to keep my headphone from collecting dust. Very happy with it as my first amp and from my research I think One is the best $150 amp for most headphones.

Decent amp with good power output if you like THX amps
Puts out 2.7 watts at 32 ohms which is pretty good, but I personally think it suffers from the THX compression quality as my Fiio K5 pro has more detail in some tracks.

Pretty much- Wow!
I have had the THX One for about 6 weeks now and I am really impressed with the sound quality- Neutral, natural and so real like you are in the studio or hall with the musicians. No listening fatigue. I have tried over 10 different headphones and they all sound better with The One in mho. A few of the phones that I tried- Beyerdynamic DT770 and DT990, Sennheiser 58X and 280 Pro and CAD Sessions. the build quality of the amp is very good and at the $150 mark is a steal. I have tried many amps under $200 and this is the best one I have heard. I highly recommend.

Good Value at $150. More than enough power for most.
Few references, i listen to metal, rock, jazz, rap, quite a bit of pop and a little electronic but not much. I have THX AAA one, iFi Zen DAC V2. And have JBL LSR308 studio monitors in an untreated mid size room for my personal `natural` reference. Headphones are 6XX, 58X, HE-X4, Dan Clark Aeon Closed X, Philips X2HR, DT770. These pretty much drive everything i threw at it more than fine. Amp needs for headphones in the community are over exaggerated. However once you start heavily EQ’ing low sensitivity and/or high impedance headphones and start reducing the digital pre-amp to prevent clipping, yeah some of these headphones need a quite a bit of power. (Like HE-X4’s, DT770s and 6XX) But i will be honest, i drove all these with EQ and low pre-amp settings, directly out of my iFi Zen Dac V2 and they were just fine. Really don’t need more. So why did i get it? Mostly because i wanted an amp and it’s fun! Also future headroom if i ever end up getting crazy hard to drive headphones! One excellent feature that perfectly fit my use case is they are also a great pre-amp with a dedicated button!!! So i can switch between my active studio monitors and headphone with just one button. I love that and would get this just for that! Their build is so nice, buttons and dials feel quality and the aluminium enclosure feels solid, also helps prevent sliding around on the desk. Oh they make no difference to the sound, people really imagine stuff sometimes lol. (Excluding high output impedance and/or tube amps) Haven’t used sensitive IEM’s with these much, except KZ ZSN 10pros. I don’t know why people use super sensitive IEMs with -Amplifiers-…. Like what’s the point??? It’s already super sensitive lol, but anyway their noise floor is so low, zero buzz… For reference JBL LSR308 monitors are considered okay in this sense and they have a super light buzz and i can easily hear that and it annoys me quite a bit when they are not playing. So this amp an absolute champion there. $200 a bit stretch though, i hear there are so many good amps with plenty of power out on the market. You might want to compare. At $150, easy recommendation though…

Amazing amp for the price
I bought this on sale for $150 and I'm glad I did. The sound quality is unmatched and it gets the job done. It was definitely worth spending a little extra than I initially planned.

AMP works really well! I have no complaints. The sound is very crisp and clean. I am running the dt 770's and the sound is very clear. The packaging is also very nice.

Gets the job done, and does the job well
I bought these while they were on sale for 150$ and It certainly gets the job done I upgraded from a Schiit Magni Heresy due to it's scratchy potentiometer and inability to drive sensitive IEMs as there was a channel imbalance if you go to low. The THX AAA ONE fixed these issues as the pot doesn't make ny noise at all when being moved, and the lowest gain setting works great for sensitive IEMs and there isn't a channel imbalance at low volumes. Both are pretty clean amps so I didn't notice much of a sound difference, though the THX does sound a little cleaner to me, but that could just be placebo. Also nice packaging The only downside so far is that this AMP is massive compared to it's competitors, though I knew this before buying it so I don't care that much. TL;DR: Bought so it would work with everything from sensitive IEMs to hard to drive over eras and it does both very well.

Now I understand why audiophiles quest for true FLAT/NEUTRAL sound!
