Can't go wrong for the price
Very happy with it, doesn't have a balanced out like the 789 but that doesn't bother me. The only thing wrong is the audio knob doesn't rotate around the centre, almost like a screw has been threaded wrong, only noticed it after a week of use so it's just a small aesthetic thing

I love it! I really do.
Before I got this, I was convinced that my Audeze LCD2C were faulty, because there was always a hiss and a crackle at certain higher end pitches and vocals (I won't pretend to explain this in Hz). I was using a Schiit Vali 2 with a Deagonfly Red with my Sennheiser HD6XX before and as a set they sounded incredible, even with the Monoprice M1080 the Valli 2 - Dragon Red combo sounded fantastic: but with the Audeze LCD2C things were harsh, brittle and empty; really underwelling (especially compared with the demo I head in store). NOW THIS! The THX AAA ONE has stepped in and saved the day. Even feeding it via my iPhoneX (tidal) over the Dragon Red (sofa listening), this THX amp sounds incredible. It actually did take a bit of time to warm up: the green light gets stronger. I fell asleep listing to Mad Season Above Delux Edition and woke up to Mark Lanegan, has never sounded so smooth. Honestly, I've been listeing to this album since I was 16 years old. It had never sounded better. So yeah, long story getting longer, it turns out my LCD2C are absolutely faultless and all I needed to do was feed them more and maybe better juice. - Read somewhere there is a matching DAC? Can anyone please point me to it. Paul

세일에 잘 샀다.
마감도 좋고 포장은 오버스펙이네. 150불 가치는 충분한듯. 더 싸고 작은애들 중에 좋다고 하는 애들이 많지만 사이즈 감성이란게 있으니. 당분간 지름신은 봉인될듯.

Replaced my Asgard
I bought this amp on a hunch & am pleased that I did. I'm currently running a Gustard X16 with Audeze LCD2CB headphones and have owned way too much other gear to list. The short.. I think these THX amps are as clean as the $1K Bakoon amp I bought on Drop a decade ago with stronger dynamics(although auditory memory is fickle and I've changed a lot of gear since then so YMMV.) I'd also take this over the Schiit Heresy I owned last year; I'm not confident I could tell them apart but the build quality is nicer here. I don't like having an amp light enough that I can rip it off my shelf. Longer story is that I was running an Asgard 3 when I took delivery of the ONE, here are my impressions: Pros for the Drop AAA One Linear
  • Replacing the A3 with the Drop shows a more studio clear(cold?) atmosphere where the A3 engulfs you in warm backdrop, I struggle to describe this trait as it's almost secondary to the music but extremely important to me. This is the main reason I'm making the change over. IME the whole system needs to be capable of this crispier/colder atmosphere or it just ends up sounding warm. Every R2R or AKM velvet DAC I've owned has made previous clean amps sound more like the A3 in this regard.*
  • The A3 sounds notably rolled off up top(and further recesses the Audeze uppermids) in comparison. The overall dark sound of my system combined with the above has been killing my enjoyment of music as of late. I doesn't sound right for modern recordings(metal music.) In spite of the fact I prefer my music a touch softer/forgiving my enjoyment of such is dependent on a brighter shimmery treble; using EQ to drive the treble higher on the A3 just makes it loud without any hint of the sunlit sound I'm shooting for.
  • The Drop amp is faster or maintains superior resolution of complex passages however I do think the A3 in low-gain is sometimes faster in the bass, the THX amp is doing something I can't quite put words too where the bass can't always keep up with the upper ranges. The A3 is coherent across the range.
  • The Drop can do hard cracks with kickdrums whereas the A3 slams. Both are on equal footing in macrodynamics trading blows with different tracks. My attention is more often called to the Drop's dynamics in general.
Pros for the Asgard 3
  • The Asgard takes its share of wins as well having a more interesting timbre & the slightest extension to note decay rendering the sound more correct or live sounding.
  • The A3 is the thicker more wall-of-sound style amp, despite my specific preferences I acknowledge this may make it the better rock/metal amp in general. The Drop is thinner in tonal weight and this can take away the powerful feel of heavy music. This also gives the A3 more forward momentum(even more so in high-gain which further thickens the sound.)
  • The Drop is guilty of over-separating notes which is likely just a side-effect of its great speed rather than a unique trait, I may just be repeating what I wrote in the previous section but the Drop renders tremolo picked guitars more a string of quickly picked notes while not offering kickdrums the same instead blending them more together. The A3 is more continuous with its rendition which makes it an easier listen.
  • While both amps have provided satisfying all day listening in my system I did hear sibilance once from the One. It may be more prone to harshness(I have a high tolerance for brightness so this may crop up more with others.)
These amps are close competitors and equally matched to my ears. The choice will come down to preference.

Awesome value for $150
For my first amp, this was a great value at $150. It's able to provide ample power to my HD6xxs. Very easy to set up and looks sleek as well.

Low volume
I’ll admit I have some hearing loss, but I have to stick with my Archel Pro due to at least being able to turn the volume up to satisfying levels. I get the impression that there is barely any amp power coming out. This thing does have a really clean sound. I just wish I could hear more of it.

Are you using the gain knob on the front of the amp? Depending on the impedance of the headphone used you will want to set the gain knob to the appropriate setting.

The starting point for great sound.
When Drop had the THX One as part of Drop Prime week for $150, this was too good a deal to pass up. Ok, just a FYI, I am just starting out in Amps and good quality audio and figured this would be a good starting point to get a THX amp to experience clean sound. I have this Amp being connected up to a Aune X8 Magic DAC, which is being fed via the fixed line output with a Aune X7s connected to the variable output (The reason for this is that the x7s has no gain switch while the THX One does, so I can use the DAC pre-amp like a gain control with the x7s). So, is there something to the THX One? Yes. It makes all the little sounds that you can hear in the background more clearer, while not overpowering the original song. Needless to say, I enjoying the experience. My only gripes with the unit: The volume knob and the gain switch. It needs some white paint on the level marker. I ended up fixing mine with a white paint marker so I can see it better in the dark. Overall, it's great.

The X7S gain is controlled by the dip switches on the bottom of the unit. I keep mine set to the medium setting. I don't have any headphones that need the high setting.
