Yes, this little DAP has come in for a fair amount of criticism, most of it out of proportion. It's a miniature marvel really with quite stellar performance and functionality, especially for the size and price. I've had a couple of weeks now to get to know it well, qualify my expectations, and come to appreciate it's strengths more. You're right that the MSEB is amongst it's best features. You can really get any decent set of headphones to shine with this; if needed, extend the bass, add sparkle and air, or bring the vocals into focus, and the results can be very musically pleasing. There's a list somewhere on this forum of improvements people would like to see Hibizs implement, and they should absolutely listen to their customers' needs. Personally, I can live with the minor user interface quirks and dysfunctions, as it performs, on the whole, remarkably well, and excels at it's core function of sounding very good indeed. The one major fault, for me anyway, is the totally broken and unforgivably noisy DSD functionality. A lot of effort has gone into the sound quality of this thing so they obviously knew this was broken but cut corners and released it as is anyway. DSD is advertised as one of it's main features and it needs fixing ASAP Hidizs!
