I am personally quite interested in how well the FA-10 does detail, especially detail at the top-end, but also in bass texture. I have been stricken by how often the FA-10 is placed on the side of "smooth" and "musical," as opposed to, say, the Topping A90, or even Flux Labs own FA-10 pro, which are placed in the "analytical," "dry," maybe "neutral" department, or in any case characterized as probably too revealing for their own good, for showing all the "pimples and warts" of badly recorded material.
Well, in theory, "smooth" and "musical" sound good to me, and the Flux Labs guy I chatted with at length on facebook "diagnosed" me, almost instantly, upon hearing about my DACs and other components of choice, as being an FA-10 as opposed to FA-10 Pro guy. What concerns me, though, is how much detail, if any, gets lost in all that "smoothness" and "musicality" the FA-10 fans have been talking about. I do like detail, but without any harshness or fatigue, just like my HeKSE or Audeze LCD-4 cans handle detail and texture, but especially, without any feeling that some important dimension of detail has been sacrificed in some kind of roll-off in order to enhance that smoothness. I wish I could hear the FA-10 and the pro version or the Topping A90 in order to make a determination for myself, but since that seems impossible right now, I shall defer to the ears and judgment of forum members who have heard the two approaches. Muchas gracias.
