I have been following this thread all the way from Thailand. I decided to sell my beloved DX100 and replace it with the Lotoo Paw Gold. I must admit that I have no regret whatsoever... until today. To be fair, it is not really a regret as the LPG is really an AWESOME DAP. However, I tried to play an SACD album recorded in 24bit/352.8kHz and the LPG just refuses to play this recording in regular speed. Strangely, this recording plays perfectly on my Calyx M. Really disappointing.
Other than this, I have absolutely no complaint at all about the LPG. I love the sound signature and the LPG complements really well with my Calyx M.
