    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!
