With apologies, this is not a reply to the above but I thought I would throw in my tuppence worth. As someone before has said this isn't 'the truth', it's but one data point. I'll give you my journey first. I bought an iBasso dx50 off a mate after using iPods and you can imagine what a revelation that was...anyway a couple of months back I slipped it into my pocket while ferrying kids around but didn't zip up the pocket and inevitably it slipped out somewhere in the major city that I live along with the 300gb or so of music on cards in the case. Heartbroken....the simplicity of the UI and the beautiful sound it had... anyway I looked for a stop gap. After a bit of looking around I plumped for the Fiio M6. Disaster, the sound seems as if its behind a curtain or something, it's jut not giving enough. The UI is awfully underpowered and laggy. It didn't like the folder with Haydn string quartets in it (too big perhaps), this kept making it crash. Another solution was needed and after a bit of looking round I found the dx160 (open box) for a shade over 200 GBP. Not bad I thought, get back to the iBasso sound hopefully. Its a revelation ...beautiful sound (I'm using wired Sennheiser Momentum IIs ). A beautiful clear sound stage, wide open, very neutral. Brilliant.This is based on a few reference tracks, all FLAC. Arvo Parts Spiegel Im Speigel from Fur Alina; Brahms Piano Concerto 2 (Bernstein and Zimerman);George Bensons Breezin, Dire Straits Brothers in Arms; So What from Kind of Blue. Anyway I'm one happy listener again. If anyone finds my dx50 enjoy, its a great player..
