It's funny how subjective this hobby is. Having both myself I sold r8ii because despite more details, better control it lacked body, depth and height. For me r8ii won in detail, black background and dynamics, but it was too intense. After the last update I think that the soundstage was clearly improved, but ibasso still sounded more ... funnier for meI find too that the r8ii is thicker and more fun, though a tad less detailed and narrower.
The dx340 (which I own with the stock amp) is very wide and detailed but I find it very boring overall, even when paired with “fun” IEMs. TBH I’m not able to justify the crazy amount of hype around it. It’s a good dap, but there are better choices in the same price bracket.
