Greetings, I plan to go through all 600 of these pages, I hadn’t tested the DX200 at Canjam London as I'm perfectly happy with my WM1A and I tend to ignore daps with sub 10h battery. But there's one thing I can't do and that’s is using the Sony as a dac/amp on my pc, or use the player to stream youtube or even play the youtube vids I've downloaded, be it in mp4 vid or audio only. I like to sleep off to some playlists which the Plenue D or DP-X1 allowed. So I had bought an iFi Micro DSD Black Label. Works great with my Zeus ciems, 0 hiss, great sound. With my LCD-i4 though, not so much. Regardless of the settings, I dislike its sound signature and it gets fatiguing within 5 minutes. This leads me to thinking of selling the LCD-i4 and the Micro DSD BL, but not before I got a plan for a replacement for my PC's dac/amp. The DX200 is an option I'm starting to think about seriously. Plan would be to use the DX200 on my pc or sleep, then using WM1A for portable day cary, work commuting. I've got a few questions which I hope some of you might be able to answer, though like I said I plan to go through all the pages of this thread overtime. 1st page of this thread says AMP4 is available, but I couldn't find it on the iBasso site, nor amazon or anywhere in fact. Only found these from the Shenzhen show: https://twitter.com/orcinus_/status/891571410287472640 and here at the bottom of the page http://tieba.baidu.com/p/5249476021 Is it possible to buy the DX200 with AMP4 as bundle and from where? 4.4mm TRRRS is perfect for me, wouldn't need to switch out cables from my dap <-> pc. Would be no more use for a 3.5mm cable/jack What's the rough estimate of the battery with AMP4, say on flac, normal iem? 8h? Anyone try an Empire Zeus/r with AMP1 or 2, does it hiss? I'm guessing the AMP4 isn't out yet, as I imagine Twister6 or Whitigir would've been over 'em already.
