Honestly guys. Tried again tonite after 24 more hours (475 hour zone). This thing is a poor alternative to the DX90. Wiry, inorganic and gutless hifi. The 90 is wildly better if you have any idea how live vs reproduced music sounds. I hope they come out with a new amp module. Or that balanced utterly transforms it. Otherwise, this thing is a paperweight to me.
LOL if you're serious, then I would definitely see an audiologist. Saying this unit is sub-par to the DX90 is the equivalent of saying that a StarTak phone was more powerful than an iPhone. Now I don't know how long you've had the DX200, or if you even have the correct firmware installed. What I do know is that many of us have owned some of the highest end DAP's ever produced and find it comparable to them. The DX90 is in no way better than the DX200 according to thousands of users. The DX90 is in no way better than the DX80 according to thousands of users. Both the DX80 and DX90 are not even in the same league as the venerable DX100. That being said, the DX200 has brought the tonality, sound quality, and dynamics of that DX100 to an entirely new level.
If you have truly burned this unit in for 475 hours and have poor quality sound, tell Paul from iBasso and have them send you a new unit. I assure you that you have a lemon. Lets put it this way...on just about every single audiophile website, people are raving about this unit. I personally compared it to the AK380 and found it in league with it. I also compared it to my DX80, DX90, DX100, Cowon, and FiiO units side by side. I was not the only one amazed at this DAP. (BTW I didn't get a "free' unit, and I certainly don't work for them). But you don't have to believe me, you can hear from members here or read the many reviews online.
Seriously, speak to Paul and look into getting a replacement unit. There is something wrong with the one you have.
