I took a chance on this fine amp after seeing Z-Reviews positive comments online. I have been a musician and audio enthusiast nearly my entire life (of 66 years). I am accustomed to the sound of high quality audio gear, and have recently gone down the headphone rabbit hole. I have Sennheiser HD600 and Audeze LCD-X headphones. As I have a large CD/SACD collection, I run a Sony XA5400ES CD/SACD player digital out to an RME ADI-2 DAC and then into the headphone amp. I can only directly compare the Flux FA-12S to the Drop THX-789 amp, and to my ears the Flux amp easily outclasses the THX amp in every meaningful audio way. The Flux has a fuller, more pleasing/organic sound from top to bottom, while maintaining a very solid clean, crisp, crystal clear presentation (without undue treble harshness), with no noise that I can notice. I’m sure there are better amps out there (for MUCH more money), but this amp pleases me completely. It has a terrific build quality and overall look (I got the blue front plate, very nice indeed), and the optional remote volume control works very well for me (now a slim black remote, updated from the one seen in the online video review). It also has plenty of power on tap for me…the highest I can raise the volume control using the LCD-X’s (without my head exploding- I hate that) is around 1-o’clockish on the “high” output setting. The rear preamp RCA outs are a welcome addition as well- great flexibility indeed.
Kudos to Flux for offering such a wonderful sounding, beautifully made headphone amp at such a reasonable price. Very Highly Recommended!

Stunning. I came from a Schiit stack to this and it has so far blown me away.
I know what “scales with gear” means now. My HD6Xxs are another headphone entirely. Detail and timbre are hard to articulate, imaging came out of nowhere, clarity in the highs I thought they simply could not do are now articulate, and even a little more soundstage came from it.
My Aurorus Australis so thoroughly tricked me into forgetting it was a closed headphone I now wonder what TOTL opens would be like, be it a Borealis or something like a HD800, ZMF, Hifiman, or LCD. Detail, imaging, stage, dynamics, and musicality that defies elucidation come effortlessly, and not only distracts me from work, but drops my jaw.
This amplifier cannot be recommended enough once you’re ready to move up in the head-fi world.
Customer service was always responsive and courteous. Flux knows how to make a great amplifier and I look forward to seeing what will come next from them.
