    And this one beat them all ,and i also want to say thank you to Vitalie Sandu from soundnews who told me to wait fore the FA-10 when i told him that i wanted a new headamp and everything in the review is correct i haved the same experince whit this amp.
    And also a big thank you to the Flux Lab Acoustic people they are very serious and know very well what they are doing great people.
    And i will continue following your products,and another thing this other big wellnown headamp manufactors will have to doe some serious thinking now,when they discover Flux Lab out on the market they should do it.
    So Flux Lab keep up the good work you beat them all.

    I just spent a full day with the FA-10 and Hifiman HE6se (DAC used is Chord Mojo). The HE6se is a headset that requires maximum engagement and pushes to turn up the volume, and in this case the FA-10 ensures, it has the juice that is needed for sure, it hits hard, I feel it even in the chest!

    The reverb effects on live performances are startling, and the soundstage can get huge if the recording was intended like this : song from Queen – Love Of My Life (Live at Wembley) was a revelation of how good HE6se can be if very well driven. At the same time the sound is not colorful, it is really balanced and very realistic. When turning up the volume, the sound is never aggressive or tiring, proof again that HE6se is very well driven.

    In short, I do not know what other amps are worth but to make the very difficult Hifiman singing, the Flux is sure to be: $ 750, holy cow, in blind tests the amps at several thousand euros would have hard work for sure.

    I just received my FA-10 today. My initial impressions are that I made the right decision in picking up this amp and pairing it with the RME ADi-2 DAC FS. I like the slightly warm and musical tone of the FA-10 more so than any other solid state amp I’ve heard. The FA-10 adds body and texture to the music. The dynamics and details are superb. Bass is fast, punchy, deep and hits hard. It even extends down to the sub bass region. I can clearly hear my Susvara’s giving me music down in the sub bass region. The midrange is full, clean and balanced. The treble in my opinion is beautifully implemented. To me, the treble isn’t lacking any clarity at all. The details, extension and air are all there. The treble implementation as far as I can tell allows you freedom of the volume wheel.

    Right now, I doing some listening with the RME, FA-10, and Susvara’s. The FA-10 has no problem driving the Susvara’s. The sound is rich, detailed, full-bodied, clear, and airy. The FA-10 best attributes are on full display with the Susvara’s. It’s the best dedicated solid state headphone amp I’ve heard with them. The FA-10 is so dang musical, I love this amp!
