Man am I the only one having major problems getting this batch tool to load the old firmware ? I have a 64bit windows 8 laptop . I have followed the instructions that says to hold down the volume + and then plug the USB cable into the PC.
It shows a unnamed device and and no driver? When I do this after the failed attempt my player doesn't turn on? I have to remove the battery, and then put it back in and the player turns on. Am I going to have this problem when a new version of the next firmware is released or is it just trying to go back to the original firmware?

After you connect DX90 to pc while holding volume up button, if your prompted to find drivers, direct it to the RockUSB folder in the rkbatchtool file, if not prompted for drivers, You need to go into Device Manager on you PC, find the icon labeled with a question mark, open it up, go to Driver tab, hit update driver, direct to the folder labeled RockUSB from the rkbatchtool file you got and press update. Then you can open the rkbatchtool app, click the bottom left button and select the second option to change language to english, input the directory for the firmware you want to load at the top, then click upgrade at the bottom to start the flash.
I followed the directions and I get an error messages saying found the driver software, the hash for tis file is not present in the specified catalog file. The file is likely corrupt or the victim of tampering?
ok, thats just because the driver isnt digitally signed for win 8, to get around that you need to go to PC Settings > Update and recovery > Recovery > Advanced startup (press restart) > Troubleshoot > Advanced Options > Startup Settings > Restart > press key number 7 on your keyboard when on the screen with numbered list. When you have logged back into windows after this, the original directions again and it will work this time.
For those who are having difficulty with proper scanning with their DX90, perhaps my experience will prove helpful....
I removed the micro SD card from my DX50 where it was playing flawlessly and inserted it into my DX90. (all of my music is on the sd card, none on the internal memory) The option for scanning appeared and I selected "scan". When finished, it first appeared that my music was present but after listening to the shuffle mode for awhile, it was obvious that many of the same tunes and/or artists were being repeated. I then checked in "Albums" and found only a small number of albums and artists showing. Likewise, in "All Music", there was only a small number of files showing of what I knew was actually present. Many of the albums showed "null".
I then, leaving the card in place, accomplished a "wipe and factory reset". This was done by holding both the volume up and power button together, not by selecting from the settings menu. When this procedure was completed, once again the scan option appeared and once again I selected "Scan". This scan took about 4 or 5 minutes. (my 64gb card is nearly full) Following the completion of this scan, all of my music, albums and artists appeared exactly as in my DX50. All of my albums are by folder, one album per folder. I drag and drop from my computer and do not use itunes or any sort of tagging program.
Since then, my DX90 has performed flawlessly.

Having received a DX90, I will say that the separation and ultimate dynamics is some of the best I have heard. The amp section is excellent, exceptional and even with my fi.Q, which I regard as the best amp I have heard and having compared it to some very highly regarded home amps, I feel no need to use an external amp. Thee is power in reserve and even with complex music, the sound field does not collapse.
This little DAP is truly a music player in the highest regard. The new jacks are the best I have used, exceptional grip and perfect for mobile use. The screen is very responsive and scanning of a full 64gb card is relatively fast, a few minutes for the card. You can use the DX90 as a dac via the USB and with the OTG I am able to use a 128gb in the Micro slot and that or whatever I choose, giving me 256gb of music and on and on. What a joy this player is!
Review 4 5 2014
It should be easy to review the DX90. The best evaluation I could do would be to suggest that you listen to one. That isn't what a review is about though. And there are times when people aren't interested in purchasing something, they would like to know something about the item, for interest sake.
For me, what makes reviewing the DX90 more difficult, besides restraints on my time, is that it does so many things differently. To my ear it doesn't fit a mold, nor is it a progression of a line or a step up or down from some other DAP. I find I need to explain new terms, or to define terms in a new way that to me, is how different the DX90 is. I hear music not as something canned and electronically presented but I hear music for the sake of music. Minor occurrences, the sound, in a recording, are presented as important to the role of what I hear as the main figure, or theme. As a story has an antagonist normally the counter to the protagonist with both built on so you can understand in more depth their characters and you have the foils, who are figures that provide the fill with much less is known about them and less is built on them but they add body to the story.
So it goes so much of the time with music I have heard. The main singer comes through, the instrument and you have all the supporting singers and instruments, sometimes taking their turns but you have the main drive, the nature of what the story is about. To have a story with all characters built, would be a joy but often too time consuming and sometimes unnecessary, unless it is a very simple outlay. The DX90 is able to pull from the recording, when well done, all the characters and lays them out to be heard in a dynamic space and time that creates and auditory image that belies the recording. It does not lay bare the music with intolerance, that drives a wedge between you and the music but brings the music to a closer and more emotionally satisfying place.
I often listen to Neil Young's live recordings that I have heard so many times before. With the DX90 I am not separated, I am there, and it is mentally tangible. Recently I have started listening to Greg Brown on his solo recordings. Brown's voice, which is so individual, drives the words sings. His guitar carries the line and you can feel the connection. On these recordings you can sense the space dynamic drive of individual sounds as they emanate from the space they occupy.
I have been using the Fostex TH900 and the Hifiman 560 quite a bit in conjunction with the DX90. I also use the ESW10 JPN. The Fostex and ESW 10 are rewired with Whiplash's new gold plated silver that I find that this gets the most out of the phones and gives me the reference I am after. The Hifiman 560 is used with either the stock cable or the copper cable that comes with the HE-6. These are the main phones I have used to this point.
I have tried several amps, my favorite the fi.Q with the DX90 but I don't find it necessary, even with the HE-560. The amp section of the DX90 is a marvel. I couldn't ask anything more out of a portable amp. By using separate amps, I was able to get a handle on what the dac section and amp section are doing and what each is doing is superb. This is a case where both compliment each other. All my listening impression that I present here are done with the DX90 in total, nothing added, nothing taken away.
I write here that the dynamics of the DX90 are the best I have heard from a DAP because they are personalized to the music, the performance and not generic. There is no compression of the sound, no bleeding of frequencies, no enhancement. The bass articulates, fluctuates to the recording. The mid frequencies give justice to the human voice or anything else that falls with their realm. Highs, to my ear are extended and without edge, glare or unnaturalness. In fact the entire sound is natural. With the S/N ratio of 119 and a crosstalk of 115 comes advantages. The DX90 has a silent acoustical background that builds the music, the placement, if it is close or far off sound is replicated and offstage sounds are realistic.
Take from my review what you can, what you will. For me the DX90 takes the recording you hand it and gives you back music and that is an experience I can live with every day.
I will add more to this as time passes.
On turn on and turn off, there is a slightly audible click. This is the relay inside of the DX90 and normal.
